How to create 3 dimensions matrix in numpy , like matlab a(:,:,:) . I try to convert matlab code that create 3d matrix to python by use numpy.array and i don't know how to create 3d matrix/array in numpy
creates a 2x3x5 array. (There is also np.zeros if you want the values initialized.)
You can also reshape existing arrays:
np.arange(30) creates a 1-d array with values from 0..29. The reshape() method returns an array containing the same data with a new shape.
