You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: oxy.m
    path of file: ./repos/cmap
    
    the code of the file until where you have to start completion: 
function cm = oxy(n, varargin)
% Colormap: oxy from cmocean (data copy-pasted from ColorSchemes.jl)
    
function cm = oxy(n, varargin)
% Colormap: oxy from cmocean (data copy-pasted from ColorSchemes.jl)
% oxygen saturation in ocean water, diverging 80% of the way to represent
% a state of supersaturation. The bottom 20% of the colormap is colored
% reddish to highlight hypoxic or low oxygen water")
