pub fn io_orientations(affine: &Affine) -> OrientationsExpand description
Orientation of input axes in terms of output axes for affine
Valid for an affine transformation from p dimensions to q dimensions
(affine.shape == (q + 1, p + 1)).
The calculated orientations can be used to transform associated arrays to
best match the output orientations. If p > q, then some of the output
axes should be considered dropped in this orientation.
