What happens when the returned value is NaN? I'm using 2 arrays of observational measurements and then simulation measurements and trying to find the MSE, but upon using this algorithm I get a NaN back.

What do you want to do when there's a nan. You know there is a 'omitnans' option to mean() don't you?

OK so we know the desired signal, at least you could if you made up the equation for it. But what is the actual signal? Do you have that in some array, perhaps that you read in from some kind of position sensor or image analysis? To calculate MSE you need to have two signals - the desired/true signal, and your actual/test signal. Then just do
MSE = mean((desired - mean).^2);

Mick, not sure what your recent edit was, but if I helped you could you mark the answer as "Accepted"? Thanks.
