MATLAB Compiler

Invoking the M-File

To get a baseline reading, you can determine how long it takes the MATLAB interpreter to run gasket.m. The built-in MATLAB functions tic and toc are useful tools for measuring time.

tic; x = gasket(50000); toc
elapsed_time =
7.9620

On the Pentium Pro 200, the M-file took about 10 seconds of CPU time to calculate the first 50,000 points on the Sierpinski Gasket.

Note    The timings listed in this book were recorded on a Pentium Pro 200 MHz PC running Microsoft Windows NT. In each case, the code was executed two times and the results of the second execution were captured for this book. All of the timings listed throughout this book are for reference purposes only. They are not absolute; if you execute the same example under the same conditions, your times will probably differ from these values. Use these values as a frame of reference only.
