Examples of pythagoras.util.SingularMatrixException

pythagoras.util.SingularMatrixException
Thrown when inversion is attempted on a singular (non-invertible) matrix.

        double m20 = this.m20, m21 = this.m21;
        // compute the determinant, storing the subdeterminants for later use
        double det = m00*m11 - m10*m01;
        if (Math.abs(det) == 0f) {
            // determinant is zero; matrix is not invertible
            throw new SingularMatrixException(this.toString());
        }
        double rdet = 1f / det;
        return result.set(+m11 * rdet,
                          -m10 * rdet,
                          +(m10*m21 - m20*m11) * rdet,
