Signature

def column_stack(tup)

Summary

Stack 1-D arrays as columns into a 2-D array.

Extended Summary

Take a sequence of 1-D arrays and stack them as columns to make a single 2-D array. 2-D arrays are stacked as-is, just like with hstack. 1-D arrays are turned into 2-D columns first.

Parameters

tup : sequence of 1-D or 2-D arrays.: Arrays to stack. All of them must have the same first dimension.

Returns

stacked : 2-D array: The array formed by stacking the given arrays.

Examples

import numpy as np
a = np.array((1,2,3))
b = np.array((4,5,6))
np.column_stack((a,b))

✓

array([[1, 4],
       [2, 5],
       [3, 6]])
