`numpy.ma.extras:hsplit`

source: /numpy/lib/_shape_base_impl.py :881

Signature

def hsplit ( ary , indices_or_sections )

Summary

Split an array into multiple sub-arrays horizontally (column-wise).

Extended Summary

Please refer to the split documentation. hsplit is equivalent to split with axis=1, the array is always split along the second axis except for 1-D arrays, where it is split at axis=0.

Notes

The function is applied to both the _data and the _mask, if any.

Examples

import numpy as np
x = np.arange(16.0).reshape(4, 4)

✓

x
np.hsplit(x, 2)
np.hsplit(x, np.array([3, 6]))

✗

With a higher dimensional array the split is still along the second axis.

x = np.arange(8.0).reshape(2, 2, 2)

✓

x
np.hsplit(x, 2)

✗

With a 1-D array, the split is along axis 0.

x = np.array([0, 1, 2, 3, 4, 5])
np.hsplit(x, 2)
