#### Exercise 551

Given two matrixes A and B:

Give the numpy python code which calculates t(B)A (the inner product or dot product)

#### Solution

`import numpy as np`

A = np.array([[3,2] ,

[2,3]])

B = np.array([[1,0] ,

[4,-1]])

X = np.dot(B.T, A)

print("The product t(B)A is : " , X)

# The out put is : The product t(B)A is : [[11 14] [-2 -3]]
