error ga optimization: M must be in the range 0 <= M <= 1.

When trying to optimize a function with the ga-function in the 'Optimization Tool' I get the error: M must be in the range 0 <= M <= 1. What does this error exactly mean? Is it that the solution of my functions have to be in that range?

The problem was with a function within my function to optimize. Nothing to do with ga-function

The more information you can give us the better. How are you calling ga()? What does your function look like? A Screenshot of optimtool etc...

I'll take a blind stab at it though: I'll bet you've specified your MigrationFraction to be outside of the range of 0-1.

This is explained in the doc for gaoptimset

Thanks for your comment, but I just found out it is a problem with a function inside my evaluated function.

Then the error messages that MATLAB prints should tell you which function it is and at what line it occurs. So you should have a pretty good idea what to fix.
