Um I'm not sure exactly what your asking but you can use
glMultMatrixf() and pass in a matrix to multiply by the current matrix or just use glRotatef(),glTranslatef() for manipulating part of the matrix.

hi

I think you have to be more specific about what it is that you want before anybody can help you.

You say you want to read a matrix. Okay what kind of matrix? a specific size or just some arbitrary matrix? Aer we talking translation matrix or rotation or is it both? is it a vector?(that would be 3X1 matrix or 1X3, depending if we're using coloum vectors or row vectors)

What kind of coordinates are we talking about, 2D, 3D? Cartesian, polar or spherical?

Then you want x y z to be the solution of an equation. What equation? what are you trying to do specifically?

regards

3d -- Cartesian

solution of an equation (se) --> I do not know as to specify.they can be values of a test of heating in a cube.

My english is unfortunatelly very poor.
