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
doc gaoptimset

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.
