MATLAB Compiler

Invoking the MEX-File

Invoke the MEX-file version of gasket from the MATLAB interpreter the same way you invoke the M-file version.

• x = gasket(50000);
  

MATLAB runs the MEX-file version (gasket.mex, which is gasket.dll on the PC) rather than the M-file version (gasket.m). Given an M-file and a MEX-file with the same root name (gasket) in the same directory, the MEX-file takes precedence.

Note    To verify that the MEX-file version ran, use the which command     which gasket     D:\work\gasket.dll

To display the Sierpinski Gasket, use

• imagesc(x); colormap([1 1 1;0 0 0]);
  axis equal tight
  

Figure 3-1, The Sierpinski Gasket for 50,000 Points, shows the results.
