Generating a cosine wave with variable frequency where frequency is an output from a lookup table
I am trying to generate a sine/cosine wave with a variable frequency. Here’s how I did it.
I took a PN sequence generator with samples per frame 3 and converted those three samples in 1 frame to a decimal number by a MATLAB function block and passes it to a lookup table (1-D) as breakup points [0;1;2;3;4;5;6;7] and gave some data [100;200;300;400;500;600;700;800]. This data is given to a MATLAB function block which takes the values of the lookup table and time from clock block and gives me the result cos(2*pi*f*t). Atleast, this is what it looks like. But, when I ran it oscilloscope haven’t shown me any cosine waves rather, it showed me a constant signal of 1 unit.I am trying to generate a sine/cosine wave with a variable frequency.

Standalone mcc app cannot import class within python module
I have an app made via mcc. In this app I need to call a python 2.7 class within a python 2.7 module. I am able to insert the path to the module to the python search path via

I am also able to import the module via
py.importlib.import_module(‘module’)
whose return lists all the correct classes and modules.

Higher user rights without special group
Hello everyone,
unfortunately I have found absolutely nothing suitable.
I have a user who can always see and open all folders in the sharepoint. The user cannot change data in the folders.
I am not aware of any group or role that the user should have in contrast to all other users.
Is there a way to display the group memberships of AzureAD and Sharepoint users?
(I can’t find any differences in the normal interfaces).
Can rights come via Exchange Online?
Deputy regulations? If so, where else can I look.
In the meantime, I have even removed all permissions from this sharepoint folder and access is still possible for this user.
Many thanks for your support

Mitre information missing from incident
Greetings
I have a tough time getting the MITRE parsing to work for one of my integrations. It’s a security platform that’s sending incidents to Sentinel using CEF and they arrive into Log Analytics looking like this, it’s been truncated for clarity etc.
Now, in the analytics rule under Alert Details I’ve tried different settings for the tactics and/or techniques using either the mitre_id column or mitre_name but none of those ever show up in the incident.
Does anyone have any pointers on how to get this to work?

ForEach Activity: Immediate Pipeline Failure on Any Child Activity Failure
Hello Azure community,
I’m working with azure data factory and have a pipeline set up with a ForEach activity that runs three activities in parallel:
1. Notebook A
2. Execute Pipeline B
3. Notebook C
My requirements is to ensure that if any one of these activities fails (e.g. Child Activity A or B or C fails after 2mints of pipeline start) the entire pipeline should fail immediately, regardless of the status of other activities (still running).
Could you please guide me on how to achieve this behaviour?

Export Timetable data to Excel
I have a lot of rainfall data which has been uploaded to thingspeak. I want to download some of that data and analyse it in Excel. I was hoping to use the MATLab analysis to do this.
Bearing in mind I am fairly new to this and programming isn’t my thing.
I was hoping to use the following code which as far as I understand extracts the data in TimeTable format and then use the writetimetable function to create an Excel spreadsheet. When I run it it extracts the data and displays it as I want without error but I don’t know what happens to the xlsx file.
I’m probably missing something

Matlab crashes when Intel MKL’s function Pardiso is called
Hello everyone!
I am currently working with Matlab R2021b on Ubuntu 22.04. I am writing a program that will solve linear sparse system of equations, and I am trying to solve it with Pardiso function from Intel MKL library.

Powerpoint Copilot generates unrelated and nonsensical slides
I have been using Copilot for Office in a case that seemed perfect, namely generating slides in PowerPoint from a Word document.
I got quite strange results, i.e., the first version of the slides is good, if I then ask for a modification such as reducing the number of slides (which Copilot in the chat seems to have understood correctly), the result was repeatedly the same, i.e., it proposes me nonsensical slides about… the history of Istanbul (!?!).
I don’t have any material on Istanbul nor have I ever researched it, so I think (I hope) that it is some kind of Easter Egg popping up when Copilot doesn’t understand the command, otherwise it would be a really serious problem. In the screenshots you can see that Copilot interpreted the command correctly, but the result is completely wrong.
I repeated the same sequence several times, starting from scratch, and the result was always the same, i.e., slides about Istanbul.

Macro for cutting data, creating a new file with a prescribed filename, with multiple tabs
Hi All,
I have a clever Macro that can take the data in a File table, filter by say, a Region number, cut the data into a new Excel file and save as by Region name (or other preset name) in an output folder. It saves me hours. The challenge I have is that this raw data is all on one tab and therefore so is the output. If I have two tabs of raw data, Sheet1 & Sheet2, and a common column name – i.e Region number on both tabs, has anyone built (or can build a macro) that can do the same as above but for both tabs. So the output would be a series of new files, saved to where I need them, with a file name I can set, cut by Region number, but with two tabs of data for each Region.
Help and thanks!

how to do edit table type data and do sliding window in matlab
I have imported excel file into matlab and stored it as type of table, the file contains customers’ name, number, date of purchase and other such kind of things. now what I to do is to achieve following function in matlab: 1. I can filter specific customer’s record by entering his name 2. the showed records of this specific customer are sliding windows, every unit of the sliding windows is like from day1 to day 10 and next is from day5 to day15. so can anyone help me out ? the only hint I know is to use cell type, but I still don’t know what is the code look likeI have imported excel file into matlab and stored it as type of table, the file contains customers’ name, number, date of purchase and other such kind of things. now what I to do is to achieve following function in matlab: 1.

Motion of a square
Good morning, I am asking for a review of the code that I am leaving as an attachment. The objective of the code should be to take as input the position of 4 points inside the square (integral with respect to the square, fixed in the face). Through an analysis of the variation of the 4 x and y coordinates you want to construct a code that simulates the motion of the square built around these points. What is to appear on the screen will be a black square with 4 fixed white points inside moving in a gray plane. The data with the positions are extracted from a text file that comes from a camera capture. Thank you in advance for your help.Good morning, I am asking for a review of the code that I am leaving as an attachment.

How to get the error in two different curve ?
I have two data set , A1 and B1 are 151 datas ,and A2 and B2 are 98 datas(as the attached file Data.mat).
The image below are the two curves.
<</matlabcentral/answers/uploaded_files/129768/2.jpg>>
<</matlabcentral/answers/uploaded_files/129769/1.jpg>>
Because of the different number of these two data,I can’t subtract each value directly.
Then,How do I get the error between them ?
———————-The following steps are what I did.———————–
1. Using function ‘saveas’ to save these two image.Before saving these image, I had adjusted the X axis and Y axis in these two image to the same scale.
2. Using function ‘imread’ and ‘rgb2gray’ to read these two image and turn them into black and white graphics.
3. Using function ‘imsubtract’ to get the error between them.
——————————————————————————————
There are some disadvantage in this way.
So I want to ask the better way to slove this problem.
