README

        
FyeldGenerator repository

=========================

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

Example

-------

```python

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")

```
