Equivalent of Matlab in Python -


i have code want reference elements of m in matlab:

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

how tell python reference elements of m?

if understand code correctly, count nan elements in matrix. if so, can equivalent thing in python using numpy following code:

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

if insist on sum function, work:

np.sum(np.isnan(m))
