You can use the numpy size() function to get the total number of elements in a matrix.

Example:

>>> import numpy as np>>> a=np.asarray([[1,2,3],[4,5,6]])>>> aarray([[1, 2, 3], [4, 5, 6]])>>> np.size(a)6

>>> import numpy as np

>>> a=np.asarray([[1,2,3],[4,5,6]])

>>> a

array([[1, 2, 3],

[4, 5, 6]])

>>> np.size(a)

6

Another approach using shape:

>>> a.shape(2, 3)>>> s=a.shape>>> s[0]*s[1]6>>>

>>> a.shape

(2, 3)

>>> s=a.shape

>>> s[0]*s[1]

>>>
