How do I reduce the running time when I call thousands of 'intlinprog' ?

• 'intlinprog' is used in a subfunction that is called many times, and the running time is too long. I want to get a faster running time, so what can i do?

If the calls don't depend on each other, make a parfor loop.

Thanks, but I used 'parfor' in the main function, so this subfunction can't use 'parfor' (nesting is not allowed, right? ).

You can try to call multiple problems at once by

• Concatenate f, intcon, b, beq, lb, yb, x0,
• Make matrices A, Aeq block diagonal (possibly sparse format is better).

Not sure if it saves time or the solution is not degraded though.

Thanks, this is really something I didn't think of. I'll give it a try.

Bruno Luong, i don't know how to concatenate f, intcon, b, beq, lb, yb and x0, and could you mind explaining specifically? thank you very much.
