Plotting the Bar chart in Matlab
Hi all,
I am plotting the bar chart in matlab with the following code,
x = [1 2 3];
figure,
bar(x,[3 2 1;6 5 4;9 8 7])
Here, I am getting the following chart when I run it, but it should be (3,6,9) should be below the 1(x-axis), (2,5,8) under the 2(x-axis), similarly (1,4,7) in 3(xaxis).
It would be great, if anyone could help.
Thanks,

How to optimize matlab code about Radar Signal Process?
Hi MathWorks Team,
I received some matlab code from TI company for Radar Signal Process.
The code is too slow to use as TI didnt optimize anything about the code.
They just told me some tips to optimize the code like below.
You can use Parallel Computing Toolbox and modify the code to support parallel computation.
You can also store few intermediate results in the form of .mat file and reuse the results instead of computing it multiple times.
If there are other good ways to make better performace, please share ideas for me.

Fixed-point conversion error of dsphdl.FFT

getting name of the txsite that offers best SINR (or signal strength)
Hi All,
I am trying to put RF propagation functionality in the Antenna Toolbox to good use.
I have a scenario where there are multiple transmitters and I produce the SINR plot in a region of interest using sinr() function. My question is whether there is a way to programmatically find out the txsite that offered the best signal strength (and hence the best SINR) at a given point in the region of interest?

I am trying to put RF propagation functionality in the Antenna Toolbox to good use.
I have a scenario where there are multiple transmitters and I produce the SINR plot in a region of interest using sinr() function. My question is whether there is a way to programmatically find out the txsite that offered the best signal strength (and hence the best SINR) at a given point in the region of interest?
Thanks in advance rf propagation, txsite, sinr, rxsite MATLAB Answers — New Questions
How to call a DLL sub-function in Simulink EML suitable for use in accelerated models & generated code
I think the Summary says it all.
But please note that other sub-functions of the same DLL will be called by other EML instances in the same model (as the DLL is intended to be used as a shared/common dataset to overcome Simulink problems with passing large datasets over model reference boundaries and accelerated code generation failures).
Also I have, working perfectly well, developed mex and s-function (and tlc files) suitable for calling the DLL’s sub-functions outside of the EML. However, the model will flow better if I can do it from EML too.
And yes I know for accelerated use I can use "coder.extrinsic", but I believe that this does not work for generated code (unless you tell me I’m wrong)I think the Summary says it all.

How to disable beep on backspace. Beep off does not work.
I loaded Matlab 2023a this morning, and discovered that it had started beeping in a variety of ways, all of which are incredibly annoying. This never used to happen, so imagine my surprise when I search the problem and discover that people have been complaining about this very issue since at least 2012. I don’t know why this has suddenly become a problem, but it is infuriating. I know it sounds like a minor issue, but it has hamstrung my productivity entirely.
The command beep off does not do what it says on the label, leaving the annoying beeps on. If there is any solution that I may have overlooked in my search, I would be most appreciative.
Disabling the system sound in question has had no effect. Matlab ignores my system preferences and plays the sound anyway.
Hacky workaround: I deleted the system bell sound and rebooted, which caused Matlab to go looking for another sound. It defaulted to the freedesktop theme, which I do not use, so from there, I replaced the bell sound with silence. Without completely rebooting, it was still using the same system sound, so it’s storing a copy of it somewhere. If anyone knows where that is, or what exactly it is doing, maybe that’s a pathway to a better solution?I loaded Matlab 2023a this morning, and discovered that it had started beeping in a variety of ways, all of which are incredibly annoying.
