Rotating an image array in Numpy
Question
I have a 2D array that represents the values of an image that can be viewed with the imshow() command in matplotlib. I would like to rotate the values of this array ("Rotate the image") and have not found a way to do so with a typical NxN array. Anyone know how to do this?
Thanks for your time

How about scipy.ndimage.interpolation.rotate() ?

You should be able to use rot90 on the array to rotate it and then imshow.
