"Is there a standard lookat for matrix? Do you know
where I can get it? "

Or just create some system of equation that satisfy to
conditions . It will show the complexty of the problem.

The matrix to quat
that I have here: 
By: martinbaker ( Martin Baker

I am trying to work
out what the physical meaning of taking 3 vectors and putting them together
in a matrix is? The vector cross product has a physical meaning (a vector
which is perpendicular to the two input vectors) So can we give a physical
interpretation to the matrix operation. Is it multiply the first vector
by x, the second by y and the third by z then add them together? I'm not
sure I may have changed over the rows and columns?

Yes , thats a method that use 3 sqrt , you wrote. It is
a common method, to setup quaternion from "dir" "up"
, just look in some tutorials about camera orientation.

"I think I see
what you mean. If a point is defined in terms of a set of basis, it can
be defined in terms of another set of basis by projecting the old basis
onto the new basis."
