protected static FundamentalRefinement.FastSolveNormal3x2 solve(double[] r1,
                                             double[] r2,
                                             double[] r3)

Solve the over-determined system [r1 r2]x = [r3] where r1, r2 and r3 are 3-dimensional column vectors and x is a 2 dimensional column vector x=[r; s]. Least-squares solution is found by solving the normal equations x=(A^T * A)^-1 *(A^T * b) where [r1 r2]=A and b=r3.

Parameters:

r1 - vector 1

r2 - vector 2

r3 - vector 3

Returns:

the solution
