I have resolved using the aspect setting.
I calculated the ratio between the two pixel dimensions and I use this
value for aspect (if you want to shift the pixel size you can use the
inverse of this value).
Thank you for the support!

Actually, I think he's wanting a set aspect, right? Either way, it's
just "aspect=1.5" or "aspect=0.6667" depending on the orientation he
wants.

The solution is already the aspect='auto', ie:
import numpy as np
from matplotlib import pyplot as plt
a = np.arange(100).reshape(10,10)
plt.imshow(a, aspect='auto')
aspect='auto' is what you were looking for, the documentation (as you
probably already found is for example at:
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
or in interactive help.
