how to write file in PS using simulink
We are using a ZCU111 board and matlab/simulink to implement RFSoC logics. We are developing using the example on the Matlab website ( https://www.mathworks.com/help/soc/ug/ReceiveSignalWaveformUsingDDR4onXilinxRFSoCDevice.html ). There are PL and PS/processor in RFSoC. We want to create/generate data in PL and save data in PS.
Currently, a file has been created in PS. It is not the data we want, but it is writing something. However, after rebooting, it can no longer write data. Also, it is currently writing data to only one file, but we want to manage data events for multiple files. We are saving data in a set of FIFOs and are able to read it out to the computer, but we want to save this data as incrementally named files (event1, event2, etc.) on the PS system instead.
In other words, there are two questions.
Q1. How can we generate files per event in PS/processor?
Q2. How do we keep writing data to files even after a reboot in PS/processor?We are using a ZCU111 board and matlab/simulink to implement RFSoC logics.

Windows 11 – Outlook instance is already running when computer starts up.
When Windows boots up, sometimes I can’t open Outlook 365. Typically, ending the process and restarting Outlook works. I started checking the task manager immediately on boot up, and there are times when Outlook is already running and times when it is not. If Outlook is already running, it isn’t possible to open Outlook unless the process is ended. If Outlook is not running, there are no problems.
Is there a reason Outlook is sometimes already running when first booting up Windows? I tried searching for an answer but didn’t get very far; a lot on disabling add-ons and resetting the nav pane, which doesn’t apply to my issue.
I did run a repair, and it didn’t fix this issue.

Matlab Online S3 speed: copyfile vs. websave
I benchmarked some reads from an s3 bucket via the URL and https (with websave) and via the S3 URI (via copyfile) in Matlab Online.
I performed two benchmarks. I downloaded the same 750 MB file 10 times by websave or copyfile and calculated the average time, and then I downloaded a 119.9 MB file a single time via both methods.
The stats:
750MB file read 10 times:
copyfile via s3: 38.4165 MB/sec
websave via https: 71.8340 MB/sec
119.9MB file read once:
copyfile via s3: 9.0168 MB/sec
web save via https: 27.7525 MB/sec
I was surprised to see that accessing the URL via https was faster than reading directly from the S3 bucket on Matlab Online. I thought Matlab Online ran on AWS and I had expected direct S3 access to be faster.
Can anyone comment on whether this is the expected behavior?
Thanks

Highlight series of cells if 1st or last row contains text
Hello, I have a worksheet that contains a few rows for each employee. The ID # is in column A, and column E will contain a calculated numeric value. For each employee, I would like to highlight all rows of Column A, if any rows in column E for that employee are > 0. Note that the number of rows for each employee may vary.
I’m fine doing this with either conditional formatting or a formula.
So, in the attached:
# 111 has a value of 1 in the first row, so I would like to highlight all rows in column A for that person
# 666 has a value of 2 in the last row, so I would also like to highlight all rows for that person
IDs 222,444, and 555 don’t have 0 in all rows, so nothing is highlighted for them

Transparency Ghosting Effect in Rendering of Ellipsoid Surfaces
I have been attempting to render ellipsoids of various scales and rotations in MATLAB using the built-in ellipsoid() function; however, I have run into repeated graphical errors when rendering these for which I have been unable to pin down a cause.
Specifically, some ellipsoids will display a sort of "ghosting" effect, in which the opacity of the ellipsoid will change suddenly despite a constant FaceAlpha value. Attached are several screenshots of the issue:
I have noticed the following patterns with the ghosting:
The ghosting effect appears to depend on window size
Ellipsoids can be fully ghosted (i.e., much more transparent than expected)
The ghosting appears to happen when one axis of the ellipsoid is much shorter than the other two
The ghosting is very dependent on the camera angle
The ghosting appears to be dependent on the rotation of the ellipsoid (I have yet to generate a single axis-aligned ellipsoid that suffers from ghosting)
The ghosting happens for a wide range of FaceAlpha values
I have tested ellipsoid generation on both Windows and Linux, as well as using both R2019b and R2024a, and all display this ghosting effect for some cases (it is not predictable when or for which view angles as far as I can tell). I am using OpenGL hardware rendering on Windows.
My questions are as follows:
What is the root cause of this issue?
Is there a workaround that will work for any orientation and size of ellipsoid?
Thank you for your time.

I have sets of data that is being compared within each group. However, I need to display all of the groups on one graph so I can show how differences compare across various participants. Right now, this is the graph that I have. I would like to add sigmas between various blue, red, yellow bars depending of the results of the individual participant. Does anyone know how I could possible do that?

Pivot Table Date Grouping
I am trying to group dates in my PivotTable. All or most of the videos I’ve watched have said to right click & the option for grouping/ungrouping should be there. It’s not. I believe the dates are correctly formatted but I could be wrong (I did double check by going to the home tab & in the number section date was selected but I chose general & then long date & switch the country to UK). Still, I’m not getting the option. I also went to the data tab & clicked on group. Still, no option to group.
For reference I am using the web-based version of Excel via Microsoft365.
Any help would be appreciated.

Admin Center is inaccessible due to a pop-up from Business Advisor
Hello community members,
Is anyone aware of the Microsoft 365 admin centre issue where Business Advisor pop-up is blocking everything. The pop-up cannot be closed and any selections within the pop-up causes a page refresh, after which the pop-up presents itself again. I have tried reaching out at answers.microsoft.com, where others have also written about it, but no solution has been seen so far.

Who will be able to provide help with this? Microsoft US support is a bot voice agent who is unable to understand the issue. Could someone in this community point me in the right direction?
Kind regards,

Highlight Date Cell based on proximity to todays date AND another controlling cell
Hello Everyone,
I’ve read multiple posts on this topic but did not find one that exactly worked for me so I would appreciate everyone’s help.
My workbook currently uses conditional formatting to color-fill rows based on the value of column H. I also want to add the following date cell highlights into the mix if possible.
If employee is on “LOA-Active” (column H), I want date in column L to highlight YELLOW 1 week prior to their return date (column L) to show employee will be returning back from leave in the next week.
If employee is on “LOA – Active” (column H), I want date in column L to highlight RED once the date listed in column L has passed to show employee has not returned from leave
If employee is scheduled for a future leave “LOA – Future” (column H), I want date in column K to highlight yellow 1 week prior to date in K to show they will be going out on leave soon.
I need the controlling cell to be column H as “LOA-Active” highlights Column L whereas “LOA-Future” highlights column K. Once an employee returns from leave column H is marked as “LOA-Returned”, then moved to the very bottom of the spreadsheet. I want the column L highlights to then disappear.
That sounds like a lot once I typed it all out…….Your help is so much appreciated.

Unable to join Teams video Meeting Macbook
I’m using Microsoft Teams app on early 2015 Macbook Pro running Monterrey OS. Unable to join a video meeting with 3rd party. App gives me error The account you’re using doesn’t have access to this meeting due to org policies. Use Teams on your browser to join without using an account.” When I try the browser version it wants to log automatically into an older account (not the one on the invite). I log out and it immediately logs me back in to the older account. I can’t make the web version give me a non logged in state or log into the newer account.
The invite is on my gmail account and is synced to both Apple Calendar and Outlook Calendar. I thought that would make the invite populate to Teams Calendar but no luck. Don’t know if that would solve it anyway.
I’m at my wit’s end. Please help. 🙁
