numpy.asfortranarray¶

numpy.asfortranarray(a, dtype=None)[source]¶

Return an array laid out in Fortran order in memory.

Parameters:

Parameters:	a : array_like Input array. dtype : str or dtype object, optional By default, the data-type is inferred from the input data.
Returns:	out : ndarray The input a in Fortran, or column-major, order.

a : array_like

Input array.

dtype : str or dtype object, optional

By default, the data-type is inferred from the input data.

Returns:

out : ndarray

The input a in Fortran, or column-major, order.

Examples

>>> x = np.arange(6).reshape(2,3)
>>> y = np.asfortranarray(x)
>>> x.flags['F_CONTIGUOUS']
False
>>> y.flags['F_CONTIGUOUS']
