value2x2

public void value2x2(double a11,
            double a12,
            double a21,
            double a22)

value2x2_fast

public void value2x2_fast(double a11,
                 double a12,
                 double a21,
                 double a22)

Computes the eigenvalues of a 2 by 2 matrix using a faster but more prone to errors method. This is the typical method.

symm2x2_fast

public void symm2x2_fast(double a11,
                double a12,
                double a22)

Compute the symmetric eigenvalue using a slightly safer technique
