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;
