Smoothening using convolution with a circular kernel
The input field is convolved with a circular kernel with equal weights. Takes into account missing values.
smoothconv(z, nas)
z |
matrix with the input field to smoothen, with dimensions |
nas |
the smoothing kernel uses a radius |
The smoothened field.

z <- rnorm(64 * 64) dim(z) <- c(64, 64) zs <- smoothconv(z, 8) sd(zs) # [1] 0.07910996
