Eigen::MatrixXd lsst::ip::diffim::makeCentralDifferenceMatrix(int width, int height, int stencil, float borderPenalty, bool fitForBackground)

Build a central difference Laplacian 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

• stencil: Which type of Laplacian approximation to use

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

• fitForBackground: Fit for differential background?
