{{DISPLAYTITLE:grid_polar.m}} __NOTOC__

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)

==Arguments==

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
