Math2 - Release 1.7

The unit MATH2 offers some of the most fundamental procedures of univariate statistics (such as mean values, standard deviations, or the correlation coefficient for a series of data pairs). In addition, several more advanced mathematical methods (such as the calculation of eigenvectors and principal components, a simple clustering algorithm, and the smoothing of data) are contained in this unit. The unit MATH2 also contains a simple, yet powerful class (TCurveFit) which supports curve fitting of univariate data.

The unit MATH2 is distributed under the shareware concept (registration, including the units MATH1, VECTOR, and MATRIX, US$ 29.60) and comes together with several sample applications, the help file MATH2.HLP, and the corresponding keyword file MATH2.KWF. In order to download the unit (supports all Delphi versions (currently 1.0, 2.0, 3.0, and 4.0), and C++Builder 1.0, and 3.0), click on the filename below:
