OptiVec contains more than 3000 hand-optimized, Assembler-written functions for all floating-point and integer data types from the following fields:


1. Vectorized form of all arithmetic operators and math functions of Pascal/Delphi


2. Statistics


3. Analysis (derivatives, integrals, extrema, interpolation)


4. Fast Fourier Transform techniques for efficient convolutions, correlation analyses, spectral filtering, etc.


5. Curve fitting for a wide range of model functions from simple linear regression to general linear models


6. Graphical representation of data in Cartesian coordinates


7. Matrix operations, e.g.: multiplication, inversion, LU decomposition, singular value decomposition, two-dimensional FFT, eigenvalues


8. Complex number math


The vectorized implementation in Assembler makes OptiVec functions on the average 3-5 times faster than compiled Pascal source code of the same functionality. In many instances, the numerical accuracy is improved as well.


The Shareware version is for the real-mode DOS target of Borland (Turbo) Pascal 7.


All OptiVec functions are optimized for Pentium/Pentium Pro, but will run on computers down to 386+387. (The full version contains additional, slightly faster units, requiring 486DX.)
