11. Create a Python file called questionIpy and write the following functions: (a) (5 points def matrixMul(A, B): 'Returns the multiplication of matrix A and B If the Matrix A and B cannot be multiplied, return back suitable error message (b) (5 points) def matrixT(A): Returns the Transpose of the Matrix A (c) (5 points) def matrixAdd(A, B): Returns the addition of Matrix A and B If the Matrix A and B cannot be added, return back suitable error message'"' . You can test your code out as follows: print matrixT(A) #This prints back the transpose of A print matrixHul(A,B) #This prints back the multiplication of A and B print matrixAdd (A,B) #This prints back the addition of A and B . You can visualize, the Python code.e. list of list as the following matrix: A-2 4 7 print matrixHul (A, B) #This prints back the multiplication of A and B For the above test case, your code will print out the following: [012, 19, 67], [17, 27, 96], [3, 6, 13]] B= [[1], [1], [1]] #This is a column vector print matrixMul (A,B) For the above test case, your code will print out the following Make sure to use Python 2.7.x when writing your code
