Download a Shareware Version

To let you "try before buy" our products, evaluation versions are available for free download.
These Shareware versions of OptiVec and CMATH can be used for a full 90 days, before they cease functioning and remind you to get a registered copy.

The Shareware version of OptiVec comes with two libraries:

1. The P7M library, which is optimized for multi-core processors and uses SIMD instructions to speed up floating-point operations. This library requires, at least, Core2Duo or AMD64x2. Systems with several discrete processors of the Pentium 4+ level are also ok. Windows XP, Vista, 7, or 8 are needed for this version.
2. The P4D library for full floating-point accuracy with the widest range of processor and operating system compatibility (down to 486DX / Pentium / Ahtlon and for all 32-bit Windows versions). This library also checks for any dimension mismatches which might lead to violations of vector / matrix boundaries. Those violations would usually result in hard-to-locate memory faults much later in the program flow.

The Shareware version of CMath comes as the P4 library.

The accompanying documentation consists of HTML files. We recommend to read them using Firefox or Opera, as Microsoft IE sometimes crashes when loading these large files.

Visual C++ only: We recommend you install also the most recent redistributables from Microsoft. You can download them from www.microsoft.com/download. Enter "vcredist_x86" or "vcredist_x64" into the search field to get a list of available redistributables. For maximum compatibility, the 64-bit "Debug-DLL" libraries of OptiVec were created with VS2005, it is the Visual Studio 2005 redistributables which you need if you work with a higher version of Visual Studio.
