Vector, Matrix, and Complex Math Libraries
for PC Compilers

Vectorized Programming –
When Speed is Important

Most programs that process numerical data consist of loops. But loop overhead is unnecessarily slow.

Replacing these loops by hand-optimized, Assembler-written vector functions and matrix routines speeds up program execution by up to a factor of 2-3 and also greatly enhances numerical accuracy.

OptiVec™ brings the Power of Vectorized Programming to the PC!

OptiVec is a complete, hand-optimized set of libraries with over 4000 vector and matrix functions, and complex-number math routines.

OptiVec contains the fully vectorized forms of all operators and math functions of C/C++/Pascal/Delphi for all integer and floating-point (including complex) data types, plus many other real and complex math functions and routines for statistics, analysis, FFT techniques, curve fitting, interpolations, vector and matrix algebra, matrix decomposition, and graphics.
In parts, OptiVec overlaps with the well-known BLAS and LINPACK libraries, but features an easier nomenclature and a generally more efficient implementation.
Learn why vectorized programming pays off on PCs and how the vector functions of OptiVec help you achieve the high performance of vectorized programming in your software

OptiVec™ Consists of 3 Groups of Functions:

VectorLibVector functions
MatrixLibMatrix functions
CMATHComplex number math functions (also available separately)
The OptiVec libraries are static, no DLLs. This means only those functions which you actually need are linked into your application. Of course, you are free to include OptiVec functions in your DLLs, but there is no need to deal with yet another set of DLLs when you distribute your applications. As an exception to this principle, the CUDA-enabled OptiVec libraries require an additional DLL containing the actual CUDA code.


Once you purchase the Commercial Edition of OptiVec, you can freely distribute applications containing OptiVec functions. No run-time licenses needed for your customers!
An Educational Edition is available at a strongly reduced fee for non-commercial use.
