Hello, I am using Embedded Coder on Simulink Model (MATLAB 2022B). I want Local variables of generated code to be initialized to zero. I already unticked ‘Remove root level I/O zero initialization’ and ‘Remove internal data zero initialization’ so code shouldn’t optimize initializations. These two settings initialize Global variables to zero, but don’t initialize Local variables to zero. There is an example of generated code and how I want it to be. How can I do it? Thanks for your help.

How it is:
void step_function(uint16_t in1, uint16_t in2)
{
uint16_t Divide;
uint16_t UnitDelay1;
…

How it should be:
void step_function(uint16_t in1, uint16_t in2)
{
uint16_t Divide = 0;
uint16_t UnitDelay1 = 0;

Hi,
I have an equation which is as follows

When I solve this equation using the pdepe it shows an oscillation pattern at the edge as it is here (shown by arrow).

I changed my parameters a lot but this oscillation sometime reduces, but not zero. My bc are as follows
pl = 0;
ql = 1;

pr = 0;
qr = 1;
Can you tell how to reduce this oscillations?
Also, in the above equation, for the diffusion coefficient (sigma) the minimum value for which the pdepe converges is 1 below which the solution becomes diverging, it should not be actually.

To explain the title above, how do i get prediction for i+1 based on i and i-1 combined?

I had already done the training and got the training info inside variable net.
This is an example of the code for LSTM trained net to predict 1 value into the future from Mathworks website.

for i=1:numTimeStepsTest
[net,YPred(:,i)] = predictAndUpdateState(net,YPred(:,i-1));
end

I appreciate if anyone can help direct me to any forum/article regarding this matter if it has been answered previously.

I am creating an app in MATLAB Web App Server 2024a. Accessing the system’s clipboard using the clipboard function is not supported, as described in the unsupported functionality page. I am looking for an alternative so that users can paste the contents of their clipboard into a UITable.
Interestingly, despite the lack of support for the clipboard function, users are still able to paste text from their clipboard using the key combination to paste if they double click a cell in the table first so that there’s a flashing cursor. This leads me to believe that Web App Server is able to access the system clipboard, although I can’t seem to figure out how to do so (ie. if there’s a different function to call). Is there a way for me to access the user’s clipboard in Web App Server without the clipboard function? As it stands, users can only paste if they’ve double-clicked a cell in the table. A single click won’t do, and I’d like to add functionality to enable that.
Any insights are appreciated. Thank you!I am creating an app in MATLAB Web App Server 2024a.

Hello!

I have a simulink electric motor example that is being controlled via PWM.

I want the controller that spits out the PWM to be a Python function ( a NN controller I have written in Python INPUT: motor rpm OUT: PWM signal) — and it returns in real time floating point numbers. e.g. 2,504; 2,103 etc.

I want that to be the input for the PWM block in the Simulink model. And the output of the electric motor (rpm) to be the input for the Python function (I have a special measurement input for that function).

Has anybody had any succes with linking .py files and Simulink ?
__________________________________________________________________________________________________________
And to run the python files, do I need to containerize them or to do something special ? Because there are 5 files in the whole project which I will need. I cannot run the function alone.
