Im using this navigation style on ” http://demo.wordpressheaven.co.uk/newdecademuzik/ ” but it isnt working on ie have you got any tips on this ?

Thanks

new_matrix = zero(len(matrix1),len(matrix2[0]))

These three lines set up a brute-force loop through all the matrix elements. Wikipedia page has decent examples of how this calculation is performed

for i in range(len(matrix1)):
for j in range(len(matrix2[0])):
for k in range(len(matrix2)):

The next line performs the calculation for each new element. It’s tough to explain without lots of notation, but this page does a good job of simple examples. You’ll see that elements in the new matrix are a summation of multiplication of corresponding elements in columns of the first matrix, and rows of the second matrix. That’s a really awful sentence, but I can’t think of a simpler way to explain it. The += lets each of these multiplications accumulate on the proper element.

new_matrix[i][j] += matrix1[i][k]*matrix2[k][j]

The last line returns the new matrix, so it can be printed, stored as a variable, or whatever you like!

return show(new_matrix)

else:
# Multiply if correct dimensions
new_matrix = zero(len(matrix1),len(matrix2[0]))
for i in range(len(matrix1)):
for j in range(len(matrix2[0])):
for k in range(len(matrix2)):
new_matrix[i][j] += matrix1[i][k]*matrix2[k][j]
return show(new_matrix)

Thank you very much.

Thanks for sharing, though
