Actionscript Matrices

Hello,

I need a little help. There is an older thread on this forum about actionscript and math matrices:
http://www.kirupa.com/forum/showthread.php?t=19638

The problem is that I cannot have it working. It shows only the matrix for me:

Display matrix A
[1,2,3]
[1,3,2]
[2,4,1]

Display matrix/vector Y
Find and Display Ai – the inverse of A
Solve the equations for X and display the solution

Rest of the functions seems not to work? (although I don’t get any errors).:huh:

Any ideas? Help would be much appreciated.

Thanks,
Bogdan
