Create figures with different number of images but same sizes
I try to create 2 figures in 2 different scripts.
Script 1 looks like this:
img_sos = rand(64);
img_oar_pixel = rand(64);
img_oar_block = rand(64);
img_sos = img_sos / max(img_sos(:));
img_oar_pixel = img_oar_pixel / max(img_oar_pixel(:));
img_oar_block = img_oar_block / max(img_oar_block(:));
f = figure;
tl = tiledlayout(1, 3, ‘TileSpacing’, ‘compact’, ‘Padding’, ‘compact’);
clim1 = [0 1];
cmap1 = jet;
ax1 = [];
ax1(1) = nexttile;
imagesc(img_sos, clim1);
axis image off;
title(‘Sum-of-Squares’, ‘FontSize’, 10);
ax1(2) = nexttile;
imagesc(img_oar_pixel, clim1);
axis image off;
title(‘Adaptive Kombination (Pixelweise)’, ‘FontSize’, 10);
ax1(3) = nexttile;
imagesc(img_oar_block, clim1);
axis image off;
title(‘Adaptive Kombination (Blockweise)’, ‘FontSize’, 10);
set(ax1, ‘Colormap’, cmap1);
cb1 = colorbar(ax1(end), ‘eastoutside’);
cb1.Label.String = ‘Normierte Signalintensität’;
cb1.Label.FontSize = 10;
cb1.Ticks = 0:0.2:1;
My second script looks like this:
figure; %<—Matt J added
img_oar_rec = rand(64);
img_oar_rec = img_oar_rec/max(img_oar_rec(:));
img_mask = rand(64);

Request for Guidance and Resources for Electric Powertrain Control Project – Formula Student
I am currently developing a Simulink-based model for controlling the current delivered to a dual-motor inverter system in an electric powertrain, as part of a Formula Student vehicle project.
The controller will run on an embedded unit and will be responsible for computing the reference currents based on various inputs, such as vehicle speed, throttle position, and steering angle. The model will eventually be converted to C code using MATLAB tools for deployment on the ECU.
I already have experience using MATLAB and Simulink and would like to ask if you have any guidance, documentation, or reference Simulink models relevant to electric powertrain current control, inverter control, or electric motor control systems. I would also appreciate your advice on which MATLAB/Simulink toolboxes or add-ons are best suited for this type of application.

How to Apply Multiple BC Types (Dirichlet, Robin, Neumann) on a Single 3D Face?
Hello MATLAB Community,
I am trying to solve a 3D transient heat transfer problem on a simple cuboid using the PDE Toolbox.
My main challenge is applying three different types of boundary conditions to different regions of a single face.
Problem Description:
The geometry is a simple 3D block. The boundary conditions are:
Back Face (x=0): Constant temperature (Dirichlet condition).
All 4 Side Faces (in Y and Z): Adiabatic (zero flux / Neumann).
Front Face (x=L): This face needs a composite boundary condition, as shown in this diagram:
A central rectangular region with a constant temperature (Dirichlet).
Regions above and below the central patch with convection (Robin).
Regions to the left and right of the central patch which are adiabatic (Neumann).
What is the correct programmatic method to define these different types of boundary conditions on sub-regions of a single face, especially in a version of MATLAB that does not seem to support the more recent, flexible function handle syntaxes?Hello MATLAB Community,

Microsoft Graph PowerShell SDK V2.29 Now Available
New Version Released on July 9
On July 9, 2025, Microsoft released V2.29 of the Microsoft Graph PowerShell SDK to the PowerShell Gallery (Figure 1). The release notes are available but don’t really throw much light into what’s been updated and the set of issues registered in GitHub for the SDK hasn’t gone down, so it’s hard to know exactly what changes Microsoft has made in V2.29. The only way to check is to install V2.29 and run some cmdlets, which is what I did. I used the script described in this article to refresh my PC and picked up recent updates for SharePoint Online and Teams along with the SDK.
Azure AD PowerShell Finally Going Away
Microsoft recently set the final (no, it won’t be shifted again) retirement date for the Azure AD and Azure AD Preview modules. The underlying infrastructure powering these modules will be turned off in mid-October 2025. It’s not like the slow withdrawal of the MSOL module where some cmdlets (license management) stopped working and others limped on until the module’s retirement in March 2025. Once the shutters come down in mid-October, the Azure AD cmdlets stop working and scripts fail. It’s time to migrate code to use the Microsoft Graph PowerShell SDK, or if you insist, the Entra module (which is based on the SDK).
Testing Microsoft Graph PowerShell SDK V2.29
Migrating to an unstable platform is a bad idea, and the sad fact about the Microsoft Graph PowerShell SDK is that some recent versions have been unmitigated disasters. Released in May, V2.28 of the SDK fixed many problems. The good news is that the suite of commands that I use to test new SDK versions uncovered no problems in dealing with users, groups, sites, mailboxes, and other objects. The new version seems to be as stable as V2.28.
Given the size of the SDK and the number of cmdlets (44,555 spread across the V1.0 and beta modules according to the Get-Command cmdlet), there’s no way that the tests I do will reveal every potential problem in an SDK release. All I can say is that the code in the scripts that I use for testing work without a problem. You can download many of the scripts that I test with from the Office 365 for IT Pros GitHub repository.
Before committing to upgrading a production environment to V2.29, I suggest that you update a couple of workstations and test scripts there. If everything checks out, you can then proceed with a tenant-wide rollout.
Azure Automation Blues
When Microsoft released V2.28 of the SDK, they acknowledged a problem with PowerShell V7.2/V7.1 runtime support in Azure Automation. In a nutshell, it all comes down to the version of .NET supported by the SDK. Microsoft said that the problem would be resolved when Azure Automation supported the V7.4 PowerShell runtime. At the time, support was supposed to appear around June 15. That date was missed and when I checked today, only Azure Automation runbooks configured for the V5.1 runtime worked. V7.1 and V7.2 runbooks barf with an “Invalid JWT access token” error caused because the Connect-MgGraph cmdlet cannot run to authenticate the session.
Until you hear differently, stay with PowerShell V5.1 for your Azure Automation runbooks. Microsoft will eventually get all of the pieces that it owns and maintains into alignment. It’s just sad when obvious gaps appear between important Microsoft 365 automation components.
Still Positive
Despite the recent issues with the Microsoft Graph PowerShell SDK, I’m still very positive about the SDK. Sure, there’s a learning curve to master when coming from more traditional modules like Azure AD. Yes, the issues are maddening and Microsoft’s seeming inability to drive quality in an essential component is infuriating. But despite all that, the SDK allows you to get behind the scenes of Microsoft 365 in a PowerShell-friendly manner, and that’s what really counts.

MATLAB /Simulink Fundamental question
Hey guys – just wondering, what is the best way to model a given system ? I understand matlab code may look messy and hard to follow, especially for a big model but my gut feeling is that it would run faster than a simulink equivalent (I’ve tested this with a dummy model).
What do you guys think ? Is there a particular set of factors that are key in making a decision as to whether a system should be modelled in matlab or simulink ? Any thoughts appreciated !
Many thanks

Easier Configuration Promised for the Microsoft Authenticator App
Authenticator Embraces a New Method for Account Backup and Restore
My article about adding QR codes to the Microsoft Authenticator app for Entra ID guest accounts is one of the more popular on the Office365itpros.com site. Given the increasing use of multifactor authentication to protect Microsoft 365 accounts and the need for stronger authentication methods to replace insecure SMS-based challenges, it’s unsurprising that the Authenticator app is a popular choice. The app is easy to use and it’s a strong authentication method, so many boxes are ticked.
Where the Authenticator app falls down is when a user gets a new phone, either by choice or through necessity. The gloss of buying a brand-new iPhone is diminished by the pain of reconfiguring the authenticator app to regain access to accounts. Microsoft wants to remove that pain with a “more seamless and secure backup and restore experience using iCloud and iCloud Keychain.”
The change is reported in message center notification MC1111780 (8 July 2025) and will be delivered in an app update that’s expected to roll out in September 2025 with full worldwide deployment scheduled to complete in October 2025. Tenant administrators cannot affect the progress of the roll out, and the change is effective after the installation of the updated app on an iOS device (the Authenticator app also supports iPad devices).
Eliminating the Need for a Microsoft Personal Account
Today, the Authenticator app needs a Microsoft personal account (Figure 1) to backup account names and third-party time-based one-time password (TOTP) credentials used by sites like GitHub and Twitter (the site issues a challenge that is satisfied by a six-digit number generated by the Authenticator app).
Instead of using a Microsoft account for backup and recovery, Authenticator will use the iCloud keychain. Setup of new devices is therefore performed completely within the iOS ecosystem, so it’s smoother and less prone to error. Users don’t have to do anything to benefit from the update. It is enabled automatically if the device runs iOS 16.0 or later and the user’s iOS account enables iCloud and iCloud keychain. It’s likely that relatively few iOS users don’t have these components enabled. Apple is very successful at convincing iOS users to move to new versions of the operating system, so the iOS 16.0 requirement is unlikely to be an issue either, especially in corporate environments.
After the update, Authenticator backs up all account names and third-party TOTP credentials using the iCloud keychain. Nothing else is backed up, specifically Entra ID credentials are not stored, so after moving to a new iOS device, users must sign into their accounts to complete setup.
A Need for User Communication
During the period between now and September 2025, Microsoft will flag the upcoming change with messages in the Authenticator app to inform users about a “new way to backup your account” on its main screen. The settings screen will have a message about replacing the existing iCloud backup mechanism with an enhanced version. It’s possible that users will generate some help desk calls when they read these messages, so organizations should consider some proactive communications to explain what’s happening in non-technical, practical terms.
Finding iOS Devices That Might be Affected
With an eye on communications, the need exists to identify the users of iOS devices that might use the Authenticator app. One of the advantages of having a large repository of PowerShell scripts is the availability of code that can be repurposed. The trick is to figure out what bits to use.
After thinking about it, I decided to reuse some code to report user-preferred authentication methods to find users who’ve opted to use push-based methods. The devices in use can be Android or iOS, so it’s necessary to refine the set to select those who use iOS. The Get-MobileDevice and Get-MobileDevice Statistics cmdlets reveal the operating system used by devices that synchronize with Exchange Online with apps like Outlook for iOS. By checking the devices used by the folks who’ve signed up for push-based methods, we can find and report the people who are actively using iOS.

Looking Forward to the Upgraded Authenticator App
I’m looking forward to the upgraded Authenticator app. My iPhone 14 is showing signs of age and it’s time to consider moving to a new iOS device (I’ve never used Android). If Microsoft’s promise is correct, the transition should be easier than ever before, and that’s a worthwhile change.

”Simulink Linearization Issue”
"MATLAB 2025a features a more professional user interface and improved computational speed, but it also introduces new error messages. I encountered a linearization failure error in Simulink while working with a jet engine model composed of T-MATS (a NASA-developed turbofan engine modeling toolbox) components. The current error message is as follows: ‘Error: STD exception ‘class std::bad_function_call’: ‘bad function call’ caught.’ It appears to be an issue with the underlying MEX function. How can I resolve this?""MATLAB 2025a features a more professional user interface and improved computational speed, but it also introduces new error messages.

Transforming graphs horizontally and vertically to properly compare
I have several files of data which, when plotted, look like the image presented. My problem is that i need them all to be laid on top of each other, with the beginning of the rise of the first sinusoidal wave matched up in the x and y. This is so that I can create an average waveform to reduce noise in the readings. Currently, my code impoorts all my text files, 30 of them, into an array and plots them using the following loop
for K = 1 : 30 %open and read the text files
S{K} = readtable(files(K));
Sr{K} = rmmissing(S{K}); %remove NaN values from the text files
end
for K = 1 : 30 %plot each indivdual graph for comparisons
plot(Sr{K}.(1), Sr{K}.(2), ‘displayname’, files(K));
hold on
end
I know how to transform them all individually, but cannot figure out how to make it all happen at once. I attempted to use a matchFeatures command, but could not figure out precisely how to do what I wished.
The goal is for the first graph to look similar to the second, where the initial rise is matched, allowing the peaks to be easily compared.
Any help would be appreciated, thank you!I have several files of data which, when plotted, look like the image presented.

Find the centers of multiple polygons
I have an nx3 matrix that holds the locations for the vertices of a chain of hexagonal shapes (images 1, 2).
Side-note: The coordinates for the vertices of these hexagons are not in any logical order within the matrix. The coordinates were retrieved from an STL file which may be the reason why.
<</matlabcentral/answers/uploaded_files/14983/1.png>>
<</matlabcentral/answers/uploaded_files/14984/2.png>>
I’m trying to find the centroid of each of these hexagons and index those six points to its respective centroid. Once I’ve indexed these, I plan on writing some more code to manipulate the six points farther away from their respective centroids – making the hexagons larger and making my structure thicker [ _they are currently too thin_ ] (image 3).
<</matlabcentral/answers/uploaded_files/14985/3.png>>
My problem is the centroid and indexing part. I’ve tried clustering the hexagons into n/6 clusters using the k-means and subclust functions, but there’re always points that do not fall in the center of a hexagon (image 4).
