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 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.
2. The P7M library, which is optimized for multi-core processors and uses SIMD instructions to speed up floating-point operations at the expense of 1-3 digits of accuracy. This library requires, at least, Core2Duo or AMD64x2. Systems with several discrete processors of the Pentium 4+ level are also ok. Windows XP, Vista, or 7 are needed for this version.

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.

Alternatively, especially if you experience any download difficulties, we recommend that you click here to download through the Simtel.Net network instead, which has many mirror sites all over the world!

In order to use the 64-bit version of OptiVec for Visual C++, you may also have to install an updated redistributable from Microsoft. Choose vcredist_x64.exe.
