Please decide, if you want to run a C-program, like in the header, *or* a Matlab program, like in the body of the question.

You do not have to restart Matlab to run a Matlab program. It is much faster to do this in a loop inside Matlab.

diary('D:\Temp\Result.txt');
for i = 1:10000
  callYourFunction()
end
diary('off');

Of course you can use other methods than diary to create the log file, e.g.:

Str = evalc('callYourFunction')

and append the string Str to a text file. There are more possibilities, but currently the problem description is not clear enough to decide for a solution.

Thanks for your answer, i couldn't get it how it can be used to run program for multiple times. please provide me with an example.

[Walter Roberson]

You put the command in a loop, possibly passing arguments to the command. For example,

matlab -r "YourFunction(%NUM%); quit" > OUT%NUM%.txt

(I do not have much experience in Windows BAT files so the above is not intended to be exact syntax.)

Sorry, as I indicated, I do not have much experience with Windows BAT files. At home I am running all Mac, and at work I only have access to Linux systems.
