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 C/C++
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 non-linear models with multiple data sets
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 2-3 times faster than compiled C/C++ source code of the same functionality. In many instances, the numerical accuracy is improved as well. This version is for Borland C/C++ 4.0 or higher, or Borland C++ Builder (all versions) with Windows 95, 98, NT.
All OptiVec functions have been optimized for Pentium/Pentium II, but will run on hardware down to 486DX.
