Simulink Support Package for Parrot Minidrones flight log analyze
I am conducting flight tests using the Simulink Support Package for Parrot Minidrones.
After completing the flight tests, I am analyzing the flight log and encountered the following motor values: [motor values: 301.137787 -294.847717 272.892029 -285.380737].
I am unsure whether these motor values are in the units of PWM, rad/s, or rpm.
Could you please let me know where I can find this information?I am conducting flight tests using the Simulink Support Package for Parrot Minidrones.

Designfilt and bandstopfir adds +320dB for some reason
Good evening!
I am trying to create a set of FIR filters (using designfilt) to apply to some audio signals, and I’m having an issue.
When I try to use a ‘bandstopfir’, for some reason the whole signal is amplified around +320dB (while ‘bandpassfir’, ‘lowpassfir’ and ‘highpassfir’ are working correctly)
Here’s a quick example of the code I’m using, and I added the resulting images of each of these cases showing the issue:
clear
filterObject1 = designfilt(‘bandstopfir’,’FilterOrder’,301,…
‘CutoffFrequency1′,2000,’CutoffFrequency2′,4000,’SampleRate’,48000);
filterObject2 = designfilt(‘bandpassfir’,’FilterOrder’,301,…
‘CutoffFrequency1′,2000,’CutoffFrequency2′,4000,’SampleRate’,48000);
Here are images using fvtool to show both filter responses:
Bandstop (incorrect behaviour):
Bandpass (expected behaviour):
Is this a bug, is the installation I’m using somehow broken, or am I doing something wrong?Good evening!

find a value & store in new variable (again)
Dear Matlab friends,
We recently posted a question about finding values and storing them in new variables:
http://www.mathworks.com/matlabcentral/answers/31471-find-a-value-store-in-new-variable
Our question remains in the sense that we would like to know how to procede when we have a matrix rathen than a cell array.
Indeed, we have a 384 x 14 matrix A, and we would like to find all occurrences of number [2] in column 1, and save corresponded value in column 2 in a new variable "new_variable":
A =
3 5 6 …
2 3 5
2 3 4
1 4 5
5 7 9
…
so the result would be:
new_variable =
2
2
The suggestion for cell arrays was
new_variable = A{2}(A{1} == 2);
We thank you very much for any suggestion!

How Does MS Word default display characteristics

Can anyone provide insight into this mechanism. I realize I havnt provided much contextual information, and can provide this if required. But I cant help thinking that this is a general implmentation issue for MS Word. Grevillea Read More

How do you customize Start Menu pins of an AD user?
I’ve got a bit of an issue. Windows 11 Pro, and this is an Active Directory user. We use Group Policy, not Intune. Also, right-click is disabled on the Start Menu and Desktop.
I’d assumed that customizing the Start Menu was as easy as creating a .JSON file and importing it via Powershell. That, or applying the .JSON file via Group Policy. It turns out you can’t apply a .JSON file using Group Policy.
Currently, the Start Menu pins are default, so they link a bunch of random Windows apps. None of the existing Start Menu pins are of use, so I’d like to remove them all and create my own.
I could not find a working solution to remove the pins, as I tried a Powershell script. I also couldn’t add any shortcuts.
I want to avoid the use of third-party software. How can I customize the Start Menu?

Windows 11 just started to chew up RAM. ~15 GB unaccounted for.
Hey guys, possible this is a known thing, but in the last few days, I’ve noticed a huge amount of memory getting consumed by seemingly nothing or some background service. Which I only really noticed since Star Citizen complained about having less than 8 GB of free memory.
I have 64 GB of RAM here, and ~15 GB is not accounted for. The consumption got so out of hand that I had to restart my computer to keep it at bay….
I sort of wonder if this is that new Windows 11 recording feature.
not sure, any ideas?
Is there any software that can tell me what’s happening in the background?

Referencing items in a document
Hi all,
I seek guidance on the best and easiest practices to achieve the following.
First, let me paint the use case.
I have a template that around 50 people will use to create new and ongoing instances of this document.
In this document, they detail how a system will be set up for their client. This setup includes many details that they document in a process flow methodology. They will mention key things like reports, rules, in-product queries, screen changes, and so on that need to be done as part of the solution.
What I am looking to achieve is that a list of each of these reports, rules, in-product queries, and screen changes are captured at the end of the document, creating a succinct list of what is needed for each. For example, the user creating the document may mention ten different reports that are needed. I, therefore, need a section called Reports, which will reference every report mentioned and the page(s) on which it was mentioned. Then, I want the same for the rules, in-product queries, and screen changes.
Since the users creating this document are not Word experts, I want it to be easy for them to “mark” in the text they are typing that this is a report. Marking this will then add it to the reports section at the end of the document.
I would love to hear people’s ideas on achieving this.

Architecture of teams tab app?
I’m looking into a teams tab integration for a web app. The idea is this teams tab app will just be a static page for now with some buttons that redirects users. When reading the docs on getting started building I noticed they tell you to provision and deploy your app. I’m wondering if this means the app is actually deployed somewhere (running on a machine) and teams just embeds it or if teams is downloading the source code when you install an app on your client? The ultimate goal is to submit this to MS to publish to the MS store but I’m having trouble understanding what is actually being hosted and how teams accesses the content.

New Outlook Desktop 365 Add-ins Not Showing on Secondary Mailboxes
I’m testing the New Outlook desktop version, and I have encountered an issue with add-ins. My primary inbox is Jeff@furni*******.com, and when I create a new email from this account, the signature add-ins load fine. I am using the CodeTwo 365 Signatures add-in, but it seems that the add-ins are displayed only for the primary default inbox and not for any other mailboxes. However, when I create a new email from another inbox, such as Jeff@edro*******.com, the add-in pane doesn’t load, and the signatures are not imported.
This problem seems specific to the new Outlook desktop version. When I use the Outlook web app at https://outlook.office365.com/ or the old Outlook desktop version, the add-ins load correctly for all mailboxes.
It appears that the new Outlook desktop version only loads add-ins based on the primary mailbox. Even if I switch to another mailbox account, the add-ins do not load, unlike in the desktop and web versions where they load as expected once I choose another mailbox on the left pane and click compose email ill see the addins assigned to that mailbox on the editor pane.
Now if I actually change one of the mailboxes to “Set as Primary Account” the addins will load fine but only for that mailbox.

How do i extract ‘x’ and ‘y’data from ‘z’data? f(x,y)=z
I have ‘x’ data, ‘y’ data, ‘z1’ data ‘z2’ data.
It has two variable values(‘z1’, ‘z2’) at the same coordinates(x,y).
x : an integer from 1 to 13
y : an integer from 1 to 19
Z1: 13*19
I used cftool to plot the mesh. ( Interpolation)
How do I extract ‘x’ and ‘y’ data from ‘z1’ ‘z2’?
I want to estimate the coordinates by comparing the x,y data( extracted through z1)
with the x,y data (extracted through z2).
A simple example is similar to finding approximate coordinates by estimating longitude based on time and latitude based on temperature, (confined to a northern (lower hemisphere) region.)
After moving the cftool result to the workspace (name: fittedmodel_z1), in the command window, use a value with a decimal point, not an integer, within the range (~13, ~19) for x and y, such as ‘fittedmodel_z1(10.1,3.7)’ When I give the command, I can get z1 data.
How do I do it in reverse?
I want to use f(x,y)=a , but I don’t know the function f(x,y) .
Cannot use formula(fittedmodel_Z1).

After moving the cftool result to the workspace (name: fittedmodel_z1), in the command window, use a value with a decimal point, not an integer, within the range (~13, ~19) for x and y, such as ‘fittedmodel_z1(10.1,3.7)’ When I give the command, I can get z1 data.
How do I do it in reverse?
I want to use f(x,y)=a , but I don’t know the function f(x,y) .
Cannot use formula(fittedmodel_Z1).
>> formula(fittedmodel_Z1)
ans =
‘piecewise linear surface’
I just want to know the coordinates through the overlapping part like the red hatched part in the picture below.
How about using artificial intelligence like a classification model? Or fuzzy?

Different results for same equation in curve fitting
Why is custom fitting not the same as the exponential default one as shown in the picture? The data fits nicely when I use the ‘exp2’ instead.
I’m relatively new to MATLAB and this is quite baffling to me as i am unable to use a custom equation as it simply does not fit.Why is custom fitting not the same as the exponential default one as shown in the picture? The data fits nicely when I use the ‘exp2’ instead.
