Converting EMD (Empirical mode decomposition) fuction from matlab toolbox to c language

Hello,

I'm using the EMD (Empirical mode decomposition) Matlab function in PPG signal processing. I'm searching for a way to convert this function to C language.

the MATLAB C coder shows the error message " MATLAB built-in functions and toolbox functions cannot be used as entry-point in MATLAB coder". is there any method to extract the EMD function in C language.

Machine: Windows,

Version: Matlab 2018a

Any help is appreciated.

Thanks

In MATLAB Coder you cannot directy generate code from built-in functions.

Please create a wrapper function which uses the built-in function. For example :

function [imf,residual] = emd_wrapper(x) 

% Use the built-in function
[imf,residual] = emd(x);
end

Hope this will be helpful for you.
