Download PasMatLib.zip (734 468 bytes)   (version 2007.12.31 - PasMatLib-2007)

So far this download includes the Delphi code for Basic types, Linear algebra, Display routines, Special functions, Optimization, Signal processing, Data Processing, Tests/Demos.

The description of this library is here. The user guide is here (in progress). 

The unit tests require the DUnit Framework ( http://dunit.sourceforge.net/ ). Sometimes DUnit tests fail because of random choice of numeric parameters, try to run again.

In addition to the unit tests, there are several independent test and example programs (primarily related to visualization). The executables can be downloaded as demo programs:  TestDisplay.zip, TerstRandom.zip, isoline.zip, Examples.zip, Fourier.zip, TestData2D.zip, TestGrid2D.zip, TestGrid2DM.zip, TestGraph2D.zip,TestSurface.zip.

Our Pascal translation of the software from the classic textbook by Forsythe, Malcolm and Moler along with the unit test is available as an independent download FMM.zip (44 288 bytes)   (version 2004.12.30). 

Numerical methods (in preparation, so far included: uIntegration and uODE)
