good day everyone
I use the matlab toolbox script (ga toolbox). And I want to see the process and result step by step. to see this process or result, I must editing the program of ga.
but, when I already edit and continue to save this program, appear report like that " error writing ga.m...C:\program files\MATLAB\....bla bla bla...acces denied".
how to solved this problem.
thanks

To get information on the progress of the solver change the Display, OutputFcn, and/or PlotFcn options when you call the ga function. You don't need to modify the ga function at all.

thanks steven, but, I meant I want to see the step of programe not result of GA that it can see use plot funtion ect.
I modify ga function just remove (;) to see result in this step, not add new script.
thanks

I strongly recommend against modifying functions written by MathWorks. A change you think should be harmless (or that you make accidentally) could make the function stop working or make it return incorrect results.
If you need to see the process that the function follows you could set a breakpoint in the function and use the debugging capabilities to trace the execution. That would let you look at variables without making permanent changes to the file. This won't work for built-in functions for which we don't distribute the source code, but if I recall correctly ga is implemented as a regular MATLAB function file.
