Hello guys, I know I can use ; in the end of the commands to prevent them from echoing to the command windows. But now, my situation is that I have a very long code, dispersed in so many m files.

Several command in them, on purpose, for sake of reporting the status, (and useful for debugging( do not have semicolons. Now I am running the code in a loop, and I think having all these outputs slows the process.

How can I suppress all command outputs, without manually going through the long code and putting a semicolon on each line?

Bonus question: There are some disp functions as well that report to the command line. can I also suppress them?

Thanks

Thanks a lot! Worked for me for suppressing command line outputs of a model dependency function:

evalc('[files, ~, ~, ~] = dependencies.fileDependencyAnalysis(ModelName, ''manifestfile'')');

You can create a function in the current directory or top directory of the path called disp.m and put the following single line of code in there:

function thisdoesnothing (varargin)

If you need to use DISP again, just change the name of the m-file to something else (e.g. thisdoesnothing.m)

Thanks a very good solution to suppress the DISP function outputs!

Is it possible that instead of overloading disp function by creating another m-file named disp.m, I create a function named disp inside my main file (main_prog.m), but it gets a GLOBAL scope so that it also will be accessible from subcode_1.m in the run time? (subcode_1.m is called from within the main_prog.m in the run time)
