Downloads / Updates for Registered Users
Current version: 8.1.3Registered users of our products can download the present full versions of OptiVec and CMATH from this page. The ZIP files and the INSTALL.EXE files contained in them 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 need not deinstall your previous version, but simply overwrite it.
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!)
New features in v8.0 / 8.1.x:
- First Linux version, GCC and CLang
- Windows: Compatibility with newest Embarcadero compiler version RAD Studio 11 Alexandria
- Lazarus version now with Lazarus 2.0.12
- overhaul of cudaOptivec libraries, both in terms of performance increases and bug fixes
- A group of new functions, dealing with the characterization of deviations between the elements of a vector and a reference value, or between two vectors:
V?_reldiffC, V?_reldiffV relative difference (signed) V?_reldevC, V?_reldevV relative deviation (absolute values) V?_maxdevC, V?_maxdevV maximum deviation V?_maxreldevC, V?_maxreldevV maximum relative deviation V?_maxinddevC, V?_maxinddevV maximum absolute deviation and its index V?_maxindreldevC, V?_maxindreldevV maximum relative deviation and its index - Addition to the family of comparison functions:
V?_cmp_stV compare, result is true if "similar to", in the sense of "approximately equal" V?_cmp_dtV "dissimilar to", i.e. not even approximately equal V?_cmp_stVind indices of "similar" elements of two vectors V?_cmp_dtVind indices of "dissimilar" elements of two vectors V?_cnt_stV count how many elements of two vectors are similar V?_cnt_dtV count how many elements of two vectors are dissimilar - Improved handling of worker-threads for use of the autothreading libraries in DLL's: New function V_setThreadHandler allows to install callback to the thread handler of the main program (.exe), avoiding the necessity of each DLL calling V_initMT itself and working on its own threads only.
- Improved thread distribution for the matrix multiplication functions in the autothreading libraries.
- Bug fixes in
- M?_SVdecompose (64-bit), affecting also M?_safeSolve and the Linfit / MultiLinfit families.
- VCF_asin
- VD_polyfitwW
