numpy.ma.vstack

numpy.ma.vstack(tup)

Stack arrays vertically.

vstack can be used to rebuild arrays divided by vsplit.

Parameters:

tup : sequence of arrays

Tuple containing arrays to be stacked. The arrays must have the same shape along all but the first axis.

See also

array_split

Split an array into a list of multiple sub-arrays of near-equal size.

split

Split array into a list of multiple sub-arrays of equal size.

vsplit

Split array into a list of multiple sub-arrays vertically.

dsplit

Split array into a list of multiple sub-arrays along the 3rd axis (depth).

concatenate

Join arrays together.

hstack

Stack arrays in sequence horizontally (column wise).

dstack

Stack arrays in sequence depth wise (along third dimension).

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.vstack((a,b))
array([[1, 2, 3],
       [2, 3, 4]])
>>> a = np.array([[1], [2], [3]])
>>> b = np.array([[2], [3], [4]])
>>> np.vstack((a,b))
array([[1],
       [2],
       [3],
       [2],
       [3],
       [4]])
