How do I check if any elements are not a number in a matrix.

I want to check that the matrix I have contains any non numbers in it. I guess I would use the any() function? I just don't know what code to use.

a = [-2 -1 0 1 2]

isnan(1./a)

Warning: Divide by zero.

Hi,

I think you are looking for isfinite. (isNaN covers NaN values only but isfinte covers NaN as well as Inf).
