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. |
