numpy.column_stack — NumPy v1.13 Manual (original) (raw)
numpy. column_stack(tup)[source]¶
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.
| 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
a = np.array((1,2,3)) b = np.array((2,3,4)) np.column_stack((a,b)) array([[1, 2], [2, 3], [3, 4]])
