initmetagauss {rainfarmr} | R Documentation |
A Fourier spectrum with prescribed logarithimic slope and zero phases is constructed.
initmetagauss(sx, ns)
sx |
spectral slope for the output field.
The convention is that this is the slope of |
ns |
size of the output field. |
Output complex field in Fourier space with specified spectral slope,
with dimensions c(ns, ns)
