Converting from 2D coordinate Systems
I am trying to get from one 2D coordinate system to another 2D coordinate system. I found 2 corresponding points and each system. I did the following:
[a1 a2 ] * [ x1,y1 ] = [u1,v1]
[a3 a4] [ x2,y2] [u2,v2]
or A*x = u
if I use matlab to solve A = u*inv(x)
when will A be a valid transformation matrix?
Are there other methods to find transformation matrices?

This is not a homework question, i'm just doing some image processing and just need some help.
