From spatialEco v1.3-2 by Jeffrey S Evans

Gaussian Kernel

Creates a Gaussian Kernel of specified size and sigma

Usage

gaussian.kernel(sigma = 2, n = 5)

Arguments

sigma: sigma (standard deviation) of kernel (defaults 2)
n: size of symmetrical kernel (defaults to 5x5)

Value

Symmetrical (NxN) matrix of a Gaussian distribution

Examples

# NOT RUN {
  par(mfrow=c(2,2))
  persp(gaussian.kernel(sigma=1, n=27), theta = 135, 
        phi = 30, col = "grey", ltheta = -120, shade = 0.6, 
        border=NA )
  persp(gaussian.kernel(sigma=2, n=27), theta = 135, phi = 30, 
        col = "grey", ltheta = -120, shade = 0.6, border=NA )		
  persp(gaussian.kernel(sigma=3, n=27), theta = 135, phi = 30, 
        col = "grey", ltheta = -120, shade = 0.6, border=NA )				
  persp(gaussian.kernel(sigma=4, n=27), theta = 135, phi = 30,
        col = "grey", ltheta = -120, shade = 0.6, border=NA )
