Prevent anti-aliasing for imshow in matplotlib

Question

There is an interpolation option for imshow which controls how and if interpolation will be applied to the rendering of the matrix. If you try

imshow(array, interpolation="nearest")

you might get something more like you want. As an example

A=10*np.eye(10) + np.random.rand(100).reshape(10,10)
imshow(A)

imshow(A)

compared with

A=10*np.eye(10) + np.random.rand(100).reshape(10,10)
imshow(A, interpolation="nearest")
