Let A and B be two n x n matrices.

I would like to have another n x n  matrix C such that C_ij = min {A_ij, B_ij}

Example: A = numpy.array([[2,3],[10,12]]) B = numpy.array([[1,4],[9,13]])

Output

C = [[1,3],[9,12]]

The function min(axis) of numpy seems to be only unary.

Thanks.

...

numpy.minimum(A, B) array([[ 1, 3], [ 9, 12]])

In ipython:

...

numpy.min [tab] numpy.min numpy.minimum numpy.mintypecode

Try numpy.minimum: In [7]: np.minimum(A, B) Out[7]: array([[ 1, 3], [ 9, 12]])

Thanks.
