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: vega20.m
    path of file: ./repos/brainSurfer/scripts/colors/MatPlotLib
    
    the code of the file until where you have to start completion: function map = vega20(N)
% Colormap from MatPlotLib 2.0. For attractive plots using the ColorOrder.
%
%%% Syntax:
%  map = vega20
%  map = vega20(N)
%
% For MatPlotLib 2.0 improved colormaps were created for plot lines of
% categorical data. The new colormaps are introduced here:
% <http://matplotlib.org/2.0.0rc2/users/dflt_style_changes.html>
% <https://github.com/vega/vega/wiki/Scales#scale-range-literals>
% Note that VEGA10 is the new default Line Color Order for MatPlotLib 2.0.

%
%%% PLOT using matrices:

% axes('ColorOrder',vega20(N),'NextPlot','replacechildren')
% X = linspace(0,pi*3,1000);
% Y = bsxfun(@(x,n)n*sin(x+2*n*pi/N), X(:), 1:N);

% set(0,'DefaultAxesColorOrder',vega20(N))
% X = linspace(0,pi*3,1000);
% Y = bsxfun(@(x,n)n*sin(x+2*n*pi/N), X(:), 1:N);
