OptiVec contains more than 2000 hand-optimized, Assembler-written functions for all floating-point and integer data types, on the average 2-3 times faster than compiled Delphi source code of the same functionality. The following fields are covered: 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. Graphical representation of data in Cartesian coordinates. 6. Complex number math. The vectorized implementation in Assembler ensures not only superior speed: in many instances, the numerical accuracy is improved as well. All OptiVec functions are optimized for Pentium/Pentium II, but will run on computers down to 386+387. This version is for Delphi 4. OptiVec is also available for Delphi 2, Borland C++, and Visual C++.
