random matrix python
np.random.rand(3,2)convert np shape (a,) to (a,1)
# numpy array/vector (n,) dimension -> (n,1) dimension conversion
a = np.arange(3) # a.shape = (3,)
b = a.reshape((3,1)) # b.shape = (3,1)
c = b.reshape((3,)) # c.shape = (3,)
c2 = b.reshape((-1,1)) # c2.shape = (3,)NumPy Array Shape
import numpy as np
arr = np.array([1, 2, 3, 4], ndmin=5)
print(arr)
print('shape of array :', arr.shape)Copyright © 2021 Codeinu
