mmbench measures the speed of many of SDC Morphology Toolbox functions in seconds. At the end, it evaluates the speed of this computer compared to the Sun Sparc 2, using the same benchmark of the MATLAB bench function. An illustrative example of the output of mmbench is, for a MS-Windows ME Pentium III, 850MHz, 60MB RAM machine:
SDC Morphology Toolbox V1.00 Benchmark
Made on 28-Nov-2001 computer=PCWIN
