Function Documentation

Eigen::MatrixXd lsst::ip::diffim::makeForwardDifferenceMatrix(int width, int height, std::vector<int> const &orders, float borderPenalty, bool fitForBackground)

Build a forward difference regularization matrix for Delta function kernels.

Parameters

• width: Width of basis set you want to regularize

• height: Height of basis set you want to regularize

• orders: Which derivatives to penalize (1,2,3)

• borderPenalty: Amount of penalty (if any) to apply to border pixels; > 0

• fitForBackground: Fit for differential background?
