numpy.moveaxis#

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

Move axes of an array to new positions.

Other axes remain in their original order.

Parameters:

anp.ndarray

The array whose axes should be reordered.

sourceint or sequence of int

Original positions of the axes to move. These must be unique.

destinationint or sequence of int

Destination positions for each of the original axes. These must also beunique.

Returns:

resultnp.ndarray

Array with moved axes. This array is a view of the input array.

Permute the dimensions of an array.

swapaxes

Interchange two axes of an array.

>>>importnumpyasnp>>>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)
