Is there an equivalent to the MATLAB size command in Numpy In MATLAB gt gt gt a zeros 2 5 0 0 0 0 0 0 0 0 0 0 gt gt gt size a 2 5 In Python gt gt gt a zeros 2 5 gt gt gt array 0 0 0 0 0 0 0 0 0 0 gt gt gt

This is called the shape in NumPy and can be requested via the shape attribute gt gt gt a zeros 2 5 gt gt gt a shape 2 5 If you prefer a function you could also use numpy shape a

Yes numpy has a size function and shape and size are not quite the same Input import numpy as np data 1 2 3 4 5 6 7 8 arrData np array data print data print arrData size print arrData shape Output 1 2 3 4 5 6 7 8 8 size 2 4 shape

[python] size of NumPy array

This is called the "shape" in NumPy, and can be requested via the .shape attribute:

>>> a = zeros((2, 5))
>>> a.shape
(2, 5)

If you prefer a function, you could also use numpy.shape(a).
