% Compute the point spread function for a 2D gaussian.
This is the shape of a star that is effectively a point light source.
The output is unitized so the peak is 1.
Type PointSpreadFunction2DGaussian for a demo.
--------------------------------------------------------------------------
Form:
PointSpreadFunction2DGaussian;
i = PointSpreadFunction2DGaussian( p, p0, sigma )
--------------------------------------------------------------------------
------
Inputs
------
p (2,:) [x;y] positions
p0 (2,1) Center
sigma (1,1) Sigma for psf
-------
Outputs
-------
i (y,x) 2D Gaussian
