Re: radial gaussian distribution

[Shai Ayal]

will this do it or is it too simplistic?

function [x,y]=rad_randn(R,N)

  r = R*randn(N,1);
  phi = rand(N1,)*2*pi;

  x = r.*sin(phi);
  y = r.*cos(phi);

endfunction

This should generate N points with gaussian width (sigma ?) R.
both randn & rand are from octave forge.
