hi, i'm new, i have some problem this fprintf('Results from optimization In Sample \n',fid); fprintf('fid,tit1'); why this code only show one solution? "filename = junk/MRSGARCH_N.txt Results from optimization In Sample fid,tit1flag1 = 1 "

dilah - please either format the above code so that it is readable, or attach the code to your question using the paperclip button. As well, please clarify what the problem is - why do you expect more than one solution?

[diiah putrii]

I've attached my programs and data, but after trying to say the results are like this. you get to help me obtain the solution? my job is about ms-GARCH with normal distribution. I get to get ms-GARCH algorithm with matlab software?

filename = junk/MRSGARCH_N.txt ??? Error using ==> fprintf Invalid file identifier -1.

Error in ==> msgarch at 96 fprintf(fid,'Results from optimization In Sample \n');

It is printing (or not) to your file what your code is telling it to print.

See if:

fprintf(fid, 'Results from optimization In Sample \n'); 
fprintf(fid, tit1);

improves things. You might have to make similar changes in your other fprintf statements.

Remember to use:

fclose('all')

at the end of your code to close all open files.

I don’t understand your code (and I don’t have the Econometrics Toolbox so I can’t run it) so that is the limit of the help I can provide.

thanks for your answer, i'll try it :)

My pleasure!
