grid_polar.m

Generates a balanced polar grid in which the density of points does not increase towards the centre.

Syntax

[phi,r,L]=grid_polar(ncircles,rmax)

Parameters

ncircles - number of radial circles
               in the grid, an integer

    rmax     - maximum radius that the
               grid must reach

Outputs

phi      - a column vector of polar
               phi angles, radians

    rmax     - a coluim vector of radii

    L        - sparse Laplacian operator
               acting on functions defined
               as vector of values in the
               same order as the grid
