Matrix transformation parameters

Hi!
This is a question about how to generate the affine correction parameters needed to map one coordinate system to another.
I have two coordinate systems that I want to map to each other.
One of them is "true", and the other is similar but not exactly same.
I have one set of measured x,y points p1, p2, p3 in the "true" space, and one set p1', p2',p3' in the "approximate" space.I am actually measuring some marker positions on an object in two different optical microscopes with x,y position readout, and I want to "merge" the two position readouts to be the same. I take the first one as a reference, and then take the measurement from the second microscope through a transformation to get the same position readout.
Is there any function in e.g. QMatrix that can help me generate the transformation matrix parameters needed to map any point p to p'?

No, there isn't. You should do that yourself and with a proper mathematical package. It boils down to solving 2 (or 3, depending on the dimension) linear systems to determine the rows of the transformation matrix based on the initial vectors and output vectors.
