metagauss

Generate a metagaussian field

Random Fourier phases are added to the input spectrum f and an inverse FFT transform to real space is performed.

metagauss(f)

`f`	matrix with complex spectral amplitudes generated with the `initmetagauss()` function.

A metagaussian field with random Fourier phases.

f = initmetagauss(1.7, 64)
z = metagauss(f)
