% Find the blur parameter.
if v = f sigma is zero. The default for D is inf. v may be a 1 D array.
Type BlurParameter for a demo.
--------------------------------------------------------------------------
Form:
sigma = BlurParameter( f, v, r, N, lambda, D )
--------------------------------------------------------------------------
------
Inputs
------
f (1,1) Focal length (mm)
v (1,:) Distance from image plane to lens (mm)
r (1,1) Lens radius (mm)
N (1,1) F stop
lambda (1,1) Wavelength (nm)
D (1,1) Distance of the object point to the lens (mm)
-------
Outputs
-------
sigma (1,:) Blur parameter/camera parametr
