Run an M-file multiple times

I have created an M-file which gives me random stuff using random numbers. I want to run this file 1000 times. How do I do this without having to press F5 1000 times?

for ii=1:1000
    your_m_file_name %the .m is not necessary
end

Provided you are in the directory your m-file resides in, or that it is located in Matlab's path.

is that for loop in the same script as my mfile or a new mfile completely?

[José-Luis]

New m-file, or the command line. Or you could just add a loop to your script (no need for your_m_file_name then)

[Dipesh]

Also, one more thing, is the "ii" a recognized matlab command? what does it mean if its not and how would I code it into my mfile?

[José-Luis]

No, it's the loop counter. You could use other names. Look at the documentation for for:

He used ii instead of i because it's good practice not to use i or j for loop indexes because they are the imaginary variable.

Hi, I have a model with many many loops and they all have i and j. So what is at risk? Speed?
