numpy.ma.
column_stack
(*args, **kwargs) = <numpy.ma.extras._fromnxfunction_seq object>¶Stack 1-D arrays as columns into a 2-D array.
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.
Arrays to stack. All of them must have the same first dimension.
The array formed by stacking the given arrays.
Notes
The function is applied to both the _data and the _mask, if any.
Examples
>>> a = np.array((1,2,3))
>>> b = np.array((2,3,4))
>>> np.column_stack((a,b))
array([[1, 2],
[2, 3],
[3, 4]])
