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.

All timings are in seconds. - Run on an Intel Core 2 Quad, Q6600 at 2.4 GHz, with 4GB of memory
O-Matrix' performance enables me to do Mesoscale Meteorological Flow over Terrain
modeling which required a supercomputer a decade ago
