| Expression builder 1.31 is a set of eight components - TExprFunctions, TFnCategoryCombo, TFnCategoryList, TFnListBox, TVarListBox, TUserDataListBox, TExprBuilderDlg, TExprSolver, which helps you to make a custom expression builder dialogs in your applications, to enable the user to speed entering syntax valid expressions, checks them, and stores in a dataset along with any user data. TExprSolver helps you to evaluate stored expressions, it automatically fetches the values for all used in a given expression variables from an INI file and/or dataset. Full help and demo included. It needs Expression parser 3.1 to be installed. price for source: $25.00 Added: 13-02-2000/31-07-2001 | Version: 1.31 | Downloads: 4818/4719/10

| [ LeastSquareFitting.zip ] [ 176,753 bytes ] | [ Freeware ] [ With Source ] [ D6 | D7 ] | ||
| A mathematical component for finding the best fitting curve to a given set of points by minimizing the sum of the squares of the offsets ("the residuals") of the points from the curve. Demo Applications with sourcecode (linear, nonlinear, multiple regression) are included. Use of multiple regression involves the discovering of the relationship between the values and then finding an equation that satisfies that relationship.

| Probabilities package is a selection of probabilities functions: PDF, CDF and Inverse CDF for 19 different distributions (binomial, geometric, hypergeometric, negative binomial, Poisson, discrete uniform , beta, Cauchy, chi-squared, exponential, F, gamma, Maxwell, normal, Pareto, Rayleigh, Student (T), Continuous uniform, Weibull....) This code had been taken from MtxVec 1.02 and does not require any dll's, but also does not offer any vector processing acceleration routines. The package also includes a Math unit, which can serve as a replacement for default Delphi Math unit. Next to many basic math functions it also offers complete support for complex numbers.

| This component realizes a neural radial basisfunction-network (RBF-network) with three layers (input, RBF, output). The centers of the RBF-layer can be adjusted randomly, as set of the training data, or with the k-means-clustering algorithm. The training of the output weights is done using delta rule. The input of training and test data is possible via textfiles. The .zip-file contains the component as well as a short description (info.txt) and a small demo.
