OptiVec brings the power of vectorized programming to the PC. Replacing loops over data arrays by the hand-optimized, Assembler-written vector and matrix functions of OptiVec can speed up program execution by 2-3 times and enhances accuracy and safety. More than 3500 functions for math, statistics, analysis, signal processing, matrix operations, curve fitting, etc. For MS Visual C++.

OptiVec contains more than 3500 hand-optimized, machine-code-written functions for all floating-point and integer data types from the following fields: 1. Vectorized form of arithmetic operators and math functions. 2. Matrix operations, e.g.: multiplication, inversion, LU decomposition, singular value decomposition, eigenvalues. 3. Fast Fourier Transform techniques for efficient convolutions, correlation analyses, spectral filtering, etc., both one- and two-dimensional. 4. Curve fitting for a wide range of model functions from simple linear regression to non-linear models with multiple data sets. 5. Statistics. 6. Analysis (derivatives, integrals, extrema, interpolation). 7. Graphical representation of data in Cartesian coordinates. 8. Complex number math, both in cartesian and polar format. The vectorized implementation in Assembler makes OptiVec functions, on the average, 2-3 times faster than compiled source code of the same functionality. In many instances, the numerical accuracy is improved as well. Optionally, the object-oriented interface for C++, 'VecObj', offers simplified function calls and increased memory safety. This version is for Microsoft Visual C++ (Visual Studio, at least MSVC++ 5+).
