How to know if a matrix has nan?

Hi,

I have a huge matrix or table with doubles. But there might be nan in it. How do I know if there are any nan in it? I know I can use ismissing TF = ismissing(A); But TF is a huge matrix with many 0's in it. I am not sure if there are any 1's.

Thanks!

To find the number of NaN values, I would do this:

NrNaN = sum(isnan(A(:)));
