I want to multiply these two matrices using pure python. Input (M1 is 3*3 and Mt is a 3*2)
M1 = [[1.0016, 0.0, -16.0514],
[0.0, 10000.0, -40000.0],
[-16.0514, -40000.0, 160513.6437]]
Mt = [(1.0, 1.0),
(0.0, 0.25),
(0.0, 0.0625)]
Mt is zip transpose of another matrix. My code is :
def mtxmultply (X, Y):
Z = [[0 for row in range(len(X))] for col in range(len(Y[0]))]
for i in range(len(A)):
for j in range(len(Y[0])):
for k in range(len(Y)):
Z[i][j] += X[i][k]*Y[k][j]
return Z
IndexError: list index out of range. Not getting the surety if Mt is recognised as an matrix & is still a list object. But technically this should work.
