MATLAB Compiler

Code Generation Overview

Example M-Files

To generate the various files created by the Compiler, this chapter uses several different M-files -- gasket.m, foo.m, fun.m, and sample.m.

Sierpinski Gasket M-File

function theImage = gasket(numPoints)
%GASKET An image of a Sierpinski Gasket.
%   IM = GASKET(NUMPOINTS)
%
%   Example:
%   x = gasket(50000);
%   imagesc(x);colormap([0 0 0;1 1 1]);
%   axis equal tight

theImage = zeros(1000,1000);

corners = [866 1;1 500;866 1000];
startPoint = [866 1];
theRand = rand(numPoints,1);
theRand = ceil(theRand*3);

for i=1:numPoints
    startPoint = floor((corners(theRand(i),:)+startPoint)/2);
    theImage(startPoint(1),startPoint(2)) = 1;
end

foo M-File

function [a, b] = foo(x, y)
if nargout == 0
elseif nargout == 1
    a = x;
elseif nargout == 2
    a = x;
    b = y;
end

fun M-File

function a = fun(b)
a(1) = b(1) .* b(1);
a(2) = b(1) + b(2);
a(3) = b(2) / 4;

sample M-File

function y = sample( varargin )
varargin{:}
y = 0;
