clearvars function in simulink function block
显示 更早的评论
The function in a simulink function block calls another function which has an instruction given below:
clearvars -global Downsample DATAPADDING_MSECS SEARCHBUFFER Fs WHOLE_SIGNAL Align_Nfft Window
This function is giving an error:
Function 'clearvars' not supported for code generation.
I have used
coder.extrinsic("clearvars");
But the error persists, what should I do?

I am not familiar with the specific structure of your Simulink model, but I wanted to share some information from the following documentation
According to it, The code generation is not supported for "extrinsic" functions. The code generator does not produce code for the body of the extrinsic function and instead uses the MATLAB® engine to execute the call.
The line:
coder.extrinsic("function1");
will make "function1" an extrinsic function.
I think that the presence of extrinsic function in your model is not allowing code generation for your simulink model.
You can also refer to the below documentation to know more about extrinsic functions and their uses in MATLAB.

Compiled models use static allocation for global variables. Asking to clear the global would be asking to release the static memory. This is unlikely to make the memory available for use, as the allocations for dynamic memory would be a different part of the address space.
