--------------------------------------------------------------------------
Finds the output of each pixel through numerical integration.
The default plot output colors the pixels as a function of height.
A built in 2D Gaussian function is available for demos or as a
reasonable approximation to a real point spread function.
The demo is for a 64 by 64 imaging chip. As you make the imager bigger
it will slow down. For most studies you can use fewer than the full
imager.
funPSF must be of the form:
funPSF(x,y,d)
x and y are arrays passed by integral. They are two dimensional. Your
function must return the same size array. funPSF gets passed the
centroids and intensities of the point spread functions through the
data structure d as d.rPSF and d.iPSF. You can attach any other
data you want to d.funData as shown above.
Type IntegratePSFs for a demo using RHSGaussianPSF.
--------------------------------------------------------------------------
Form:
d = IntegratePSFs % default data structure
p = IntegratePSFs( d )
