O-Matrix Trig and Elementary Function Performance
The O-Matrix core functions are all highly optimized
to provide high-performance for a broad range of data analysis and
modeling applications.
The following
benchmark illustrates performance benefits for some of O-Matrix'
elementary
functions.

a 100,000 by 20 random valued matrix.- Run on a 3 GHz Pentium 4
O-Matrix' performance enables me to do Mesoscale Meteorological Flow over Terrain
modeling which required a supercomputer a decade ago
