Is there a way to save "optimoptions" to a txt file? I tried the code below but it is not working. I also tried "dlmwrite" and "writetable". Thanks for the help.

fid = fopen('GA_Results.txt','wt+');
fprintf(fid,'%s', GA_Opts);
fclose(fid);

I have never tried that.

I would save it to a .mat file. Then load it when you need it.

That's exactly the same error I got but using "save" command and saving to a mat file works perfectly. You can save both variables (GA results and optimoptions) in one call. There is also an example with txt files in the document page, it is working but it is impossible to read the txt file.

save('GA_Results.mat','GA_Opts','GA_Results')
