Registered users of our products can download the present full versions of OptiVec and CMATH from this page. In addition, here our customers who bought through an electronic distribution channel can get the rarely used libraries which are omitted from the electronically distributed versions. In order to reduce the download times, all packages are split into several parts, consisting of 
a) the documentation, 
b) the include-files (C/C++ versions only), and 
c) C++ libraries or Pascal/Delphi units for each combination of memory model and processor supported. As specified below, some rarely needed libraries are not available here, but will be sent by email upon request.

The library and unit ZIP files are password-protected. Our registered users get the passwords by e-mail. If you are a registered user and did not receive the password, please drop us a note at optivec%at%gmx.de (replace %at% by the @ sign)! Consult the documentation of your unzip program about how to uncompress password-protected files. In most cases, you will be automatically asked for the password through a popup dialogue.

You should install the files from this page over any previous version (trial or full) of OptiVec or CMATH; in other words, you should not deinstall your previous version, but simply overwrite it. If you do not have any previous version installed, you have to manually create the directories mentioned in the description below.

If you install the registered version over the Shareware version, be sure to recompile your project(s). (Remember that applications, containing functions of the Shareware version, cease functioning after 90 days and shall not run at all on your client's computers!)

Directly jump to the library selection tables:

New features in v6.0-6.5:

• Libraries for Delphi XE, XE2, and XE3
• 64-bit libraries for Visual C++ (at least Visual Studio 2005), C++ Builder / RAD Studio (at least XE3), and Delphi (at least XE2)
• Libraries employing a CUDA device (e.g., a graphics card from NVidia) for a tremendous speed-up for large vectors/matrices.
• All libraries except debug libraries treat overflow, singularity, and loss-of-precision errors "silently".
• Thread-safe nonlinear fitting functions (may now run in parallel)
• Bug fixes across the board

Update OptiVec for Embarcadero / CodeGear / Borland C/C++

1. Please download and unzip the documentation, OVDOC.ZIP, or the German version, OVDOCD.ZIP, into the OptiVec root directory on your computer. 
2. Optionally, you may also download the demo programs, OVBCDEMO.ZIP, again into the OptiVec root directory. 
3. Now please download and unzip OVINCL.ZIP, which goes into OPTIVEC/INCLUDE. 
4. Download all needed library ZIP files from the table below, store them in OPTIVEC/LIB and unzip them.

Library Type	General Purpose	Debug	Multi-Processor	Large-Vector	64-bit Gen. Purpose	64-bit Debug	64-bit Multi-Proc.
P8: AMD64xxx, Core2xxx	VCF8W	----	VCF8M	VCF8L	OVBC64_8	OVBC64_8D	OVBC64_8M
P7: Pentium 4+ / Athlon x64	VCF7W	----	VCF7M	VCF7L	----	----	----
P4: 486DX / Pentium / Athlon	VCF4W	VCF4D	VCF4M	----	----	----	----

 
The 64-bit version needs C++ Builder / RAD Studio XE3 or higher.
The Large-Vector Versions are optimized for single-processor systems for vectors and matrices larger than the size of the second-level cache of your mainboard. In these versions, the cache is bypassed during load and store operations on vector/matrix elements. A heavy penalty results from their mis-use for smaller vectors or matrices which would have fit into the cache.
The libraries for multi-processor systems run on workstations with discrete processors as well as on multi-core processors like AMD64x2, Core2 Duo and so on.
The libraries for outdated models and processors are no longer updated. The old versions are, however, still available upon request. We'll send you by email what you need.
 
5. Additionally, you need to download and link either of the following base libraries:

   Configuration	OptiVec base library
   32-bit, BC runtime library static	VCFS
   32-bit, BC runtime library as DLL	VCFD
   64-bit	OVBCx64

   
    
6. After uncompressing, you can delete all .ZIP files you downloaded.

Update CMATH for Embarcadero / CodeGear / Borland C/C++

1. Please download and unzip the documentation, CMDOC.ZIP, or the German version, CMDOCD.ZIP into the CMATH root directory on your computer.
2. Now please download and unzip CMINCL.ZIP, which goes into CMATH/INCLUDE.
3. Download all needed library ZIP files from the table below, store them in CMATH/LIB and unzip them.

Platform	P8: current processors	back-compatible to 486DX / Pentium / Athlon
32-bit Windows	CMATHF8W	CMATHF4W
Windows XP/Vista/7/8 64-bit	CMBC64_8	----

6. Please note that there is a certain inconsistency in the description of the configurations in Visual Studio: The default configurations "Debug" and "Release" actually use the runtime library and MFC as DLL. Therefore, you have to use the OptiVec base libraries OVVC??MDD.lib and OVVC??MDR.lib with these configurations. There is a problem with using these configurations, however: you always need the RTL and MFC DLL's for the specific compiler version installed on your computer. In many cases, it is therefore better to change Project / Properties / Configuration Properties / C/C++ / Code Generation / Runtime Library into "Multi-Thread Debug (/MTd)" or "Multi-Thread Release (MT)", respectively, in order to get rid of the DLL redistributables.
   On the other hand, if you do need the "RTL and MFC as DLL" configurations, you may have to install additional redistributable DLL's on your computer (and on the computers of your customers to whom you distribute your applications developped with OptiVec). You find these redistributables at 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 CUDA-enabled base libraries and all 64-bit base libraries have been created with Visual Studio 2005. So it is the Visual Studio 2005 redistributables which you need if you work with a higher version of Visual Studio.
7. Due to licence restrictions, we may not directly provide you with the CUDA import libraries you have to link to in addition to the OptiVec libraries. Therefore, you have to download and install the CUDA SDK, which is available free of charge from nVidia's web site, https://developer.nvidia.com/cuda-downloads.
   You need not know anything about CUDA in order to profit from the CUDA-enhanced OptiVec library. Just do the following things:
   1. Include the base library OVVCCUM??.lib (32-bit) or OVVCCUx64M??.lib (64-bit).
   2. Include the processor-specific OptiVec library, ending with the letter "C", e.g. OVVC7C.LIB or OVVC64_8C.lib.
   3. Include the CUDA import libraries located in $(CUDA_PATH_V5_0)\lib\win32 or $(CUDA_PATH_V5_0)\lib\x64: cudart.lib, cublas.lib, cufft.lib. Note that the DLL's to which these import libraries belong are located in $(CUDA_PATH_V5_0)\bin. The environment variable $(CUDA_PATH_V5_0) is set by the CUDA SDK installation routine. This variable is specific to the CUDA version and, consequently, will change with future updates of the CUDA SDK.

Update OptiVec for Delphi

1. Please download and unzip the documentation, OVDOC.ZIP, or the German version, OVDOCD.ZIP, into the OptiVec for Delphi root directory on your computer.
2. Optionally, you may also download the demo programs, DEMOSD.ZIP, again into the OptiVec root directory. 
3. Download and unzip the needed library ZIP files from the table below. If you previously used the Shareware version, be sure to overwrite the Shareware units with the registered ones downloaded here!
4. Installation note for Delphi 2009:
   Delphi 2009 does not offer the option to specify the unit search path in the IDE. Instead, you have to edit the .dproj file of your project manually. Open your .dproj file with a text editor, search for the entry
       <DCC_UnitSearchPath>
   and insert the correct unit path into that line.
   Luckily, this option "reappeared" from Delphi 2010 on.
