Hi,
I assume you have arrays like these:
import numpy as np
m1 = np.random.rand(size=(4,3,3))
m2 = np.random.rand(size=(4,3,3))
So that m1[0] is a 3x3 Matrix and m1[1] is another one, i.e. you have
four matrices.

or you could write the loop
m1m2 = np.empty_like(m1)
for i in range(m1m2.shape[0]):
... m1m2[i] = np.dot(m1, m2)
This should have been
... m1m2[i] = np.dot(m1[i], m2[i])
Sorry for the typo.

not, because e.g. applying it to two 3-d arrays gives
a 4-d array,
