gausskern calculates 2D Gaussian kernel based on kernel size,
deviation, and advection
Usage
gausskern(siz, sigma, muadv = 0)
Arguments
siz
size of the kernel, siz x siz. Must be a positive integer.
sigma
standard deviation of the kernel. Unit is cell width. Must be a
positive number.
muadv
advection of the kernel. Unit of the input is cell width.
Defaults to 0.
Value
Gaussian kernel as a 2D matrix of size (siz x siz)
