A method of MLSSolver.

sets the regularisation matrix of the solver, its weight times a discrete Laplacian on the grid; MATLAB’s initRegularisation

Syntax

solver.initRegularisation()

The neighbours within two halfwidths.

solver.initRegularisation(epsilon=15*degree)

Within 15 degree.

Description

Off the diagonal the matrix holds minus the dots of the grid orientations closer than epsilon, on the diagonal minus the sum of the row’s other entries. init calls it when the solver has a regularisation weight.

Input

solver MLSSolver, initialised

Keywords

keyword default description
epsilon None the radius of the neighbours, by default twice the halfwidth of the kernel

Output

solver the solver, its RM set
