numpy.moveaxis¶

numpy.moveaxis(a,source,destination)[source]¶

Move axes of an array to new positions.

Other axes remain in their original order.

New in version 1.11.0.

Parameters:	a:np.ndarray The array whose axes should be reordered. source:int or sequence of int Original positions of the axes to move. These must be unique. destination:int or sequence of int Destination positions for each of the original axes. These must also beunique.
Returns:	result:np.ndarray Array with moved axes. This array is a view of the input array.

transpose

Permute the dimensions of an array.

swapaxes

Interchange two axes of an array.

Examples

>>>x=np.zeros((3,4,5))>>>np.moveaxis(x,0,-1).shape(4, 5, 3)>>>np.moveaxis(x,-1,0).shape(5, 3, 4)

These all achieve the same result:

>>>np.transpose(x).shape(5, 4, 3)>>>np.swapaxes(x,0,-1).shape(5, 4, 3)>>>np.moveaxis(x,[0,1],[-1,-2]).shape(5, 4, 3)>>>np.moveaxis(x,[0,1,2],[-1,-2,-3]).shape(5, 4, 3)
