Hi..I am working on a program to create a rotated ellipse using 4 known points and the angle of rotation. During the process I encounter a set of homogeneous equations. Is there anyway to solve homogeneous equations in C??? Solving homogeneous equations by hand is quite differrent because you would have to assign an appropriate value to one of the variables by yourself and then obtain the other values accordingly. But how can you do that using a program?? I can't ask the user to input an approriate value everytime because it is an automated process. I am just looking for a pointer towards the logic that needs to be worked upon here. Any help would be appreciated...Thanks.
