A 2D linear coordinate transformation.
A class that computes a matrix that applies a linear transform to a 2-d Hermite polynomial expansion.
Eigen::MatrixXd getCoefficientMatrix() const
Return the matrix that maps (1-d) regular polynomials to the alternate Hermite polynomials.
Eigen::MatrixXd compute(Eigen::Matrix2d const &transform) const
Compute the matrix for a new linear transform.
Eigen::MatrixXd getInverseCoefficientMatrix() const
Return the matrix that maps (1-d) alternate Hermite polynomials to regular polynomials.
int getOrder() const
Return the maximum order at which the matrix can be computed.
