MATLAB: Finding NON in matrix

Question

Hi all In the matrix A which is 1*N matrix, I want to recognize if there is any element equal to NON in it,I replace it by zero.How can I do that?

Answer 1

I'm going to assume that you mean NaN. You can use the ISNAN function to find and replace the NaNs in your code. Here's an example:

A = randn(1,100);
A([2,10,23,47,88]) = NaN;
A(isnan(A)) = 0;
