Hi, i used Matlab for preprocessing EEG signal and i extracted some features fromm it by calculating maximum and minimum amplitude,mean and standard deviation . Also i apply for the EEG signal wavelet transform and i extarcted the energy for the details and approximations coefficient.and now i want to convert the matlab code to c code but i dont know how so can anyone please help me how to do this or give me hint ? Thanks

I tried the matlab coder but i failed because when it comes to check issues i got errors like this : wavedec is not supported for code generation detcoef is not supported for code generation

this is my matlab code

 Fs=256;
result=cell(23,1); 
for n=1:23
    deriv=(val(n,:))/2.559375;
    t=(0:length(deriv)-1)/Fs;
    result{n} = filtfilt(d1,deriv);
    moyenne{n}=mean(result{n},2); 
    variance{n} = std(result{n},[], 2);
    Maximale{n}= max(result{n},[],2);
    Minimale{n} =  min(result{n},[],2);
    [c,l]=wavedec(result{n},4,'db4');
    [cd1,cd2,cd3,cd4]=detcoef(c,l,[1,2,3,4]);
    cA4=appcoef(c,l,'db4',4);
    [Ea,Ed]=wenergy(c,l)
    energie{n} = {Ea, Ed};
end
[a,b,z,d,e,f,g,h,i,j,k,ll,m,n,o,p,q,r,s,x,u,v,w]=result{:};
