# fatty_acid.m

Spin system approximating that of a fatty acid.

## Syntax

    [sys,inter]=fatty_acid(nprotons)


## Description

This is useful in imaging simulations - the spin system returned by this function captures the essential things like chemical shift distribution and J-couplings.

## Arguments

  nprotons - the number of protons that the spin
system should have


## Outputs

  sys, inter - input data structures for Spinach
