Equivalent of Matlab in Python

Question

I have this code where I want to reference all elements of m in matlab:

 NNanm = sum(isnan(m(:)));

How would I tell python to reference all the elements of m?

Use m[:] not m(:).

If I understand your code correctly, you count all nan elements in the matrix. If so, you can do the equivalent thing in python this using numpy with the following code:

import numpy as np
np.count_nonzero(np.isnan(m))

If you insist on the sum function, this also work:

np.sum(np.isnan(m))
