Hi all,

I want to use a Matlab System or Matlab Function block in Simulink with one single equation.

After some calculations during simulink init, I obtain a function handle T = @(phi,phi_d,phi_dd). I now want to "copy" this function 'automatically' (i.e. using code) to the Matlab System file.

I realy need the automated soultion, but I have no idea how to change or generate m-files using code.

thanks for your help!

INFO - just in case it is easier to insert a string to the m-file - I obtain the function handle using

T = str2func(strcat('@(phi,phi_d,phi_dd ',func_str))

solved myself:

line1 = 'functionhead'
line2 = strcat('    T = ',func_str,';');
line3 = 'end'
Fid = fopen('filename.m','w');
fprintf(Fid, '%s\n\n%s\n\n%s', line1,line2,line3),
fclose(Fid);
