I'm trying to multiply two matrices together using pure Python. Input (X1 is a 3x3 and Xt is a 3x2):
X1 = [[1.0016, 0.0, -16.0514], [0.0, 10000.0, -40000.0], [-16.0514, -40000.0, 160513.6437]]
Xt = [(1.0, 1.0), (0.0, 0.25), (0.0, 0.0625)]
where Xt is the zip transpose of another matrix. Now here is the code:
def matrixmult (A, B):
C = [[0 for row in range(len(A))] for col in
for i in range(len(A)):
for j in range(len(B)):
for k in range(len(B)):
C[i][j] += A[i][k]*B[k][j]
The error that python gives me is this:
IndexError: list index out of range.
Now I'm not sure if Xt is recognized as a matrix and is still a list object, but technically this should work.
