Simple package to symmetric generate random field.

Project description

FyeldGenerator repository

This package provides with a quick way of generating random field having a specified power spectrum.

Example

from FyeldGenerator import generate_field
import matplotlib.pyplot as plt
import numpy as np

# Helper that generates power-law power spectrum
def Pkgen(n):
    def Pk(k):
        return np.power(k, -n)

    return Pk


# Draw samples from a normal distribution
def distrib(shape):
    a = np.random.normal(loc=0, scale=1, size=shape)
    b = np.random.normal(loc=0, scale=1, size=shape)
    return a + 1j * b


shape = (512, 512)

field = generate_field(distrib, Pkgen(2), shape)

plt.imshow(field, cmap="seismic")
