Generate the spectral amplitudes for a metagaussian field
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).

# Make a synthetic rainfall field with prescribed logarithmic spectral slope f = initmetagauss(1.7, 64) r = metagauss(f) # Check slope of the resulting field fx <- fft2d(r) fitslope(fx) # 1.640373
