Numpy - np.inner

# Multi-dimensional array example  import numpy as np a = np.array([[1,2], [3,4]]) print 'Array a:' print a b = np.array([[11, 12], [13, 14]]) print 'Array b:' print b print 'Inner product:' print np.inner(a,b)

It will produce the following output −

Array a:
[[1 2]
[3 4]]

Array b:
[[11 12]
[13 14]]

Inner product:
[[35 41]
[81 95]]

In the above case, the inner product is calculated as −

1*11+2*12, 1*13+2*14 
3*11+4*12, 3*13+4*14
