The Matrix ActiveX Component is a useful tool that can simplify the use of matrix operations for mathematical computations in application development.
It provides for matrix operations such as addition, subtraction, multiplication, inversion, transpose, and computation of determinant, LU and Cholesky decompositions. Advanced edition additionally supports QR and Singular Value (SVD) decompositions, Eigenvalue and Eigenvector computation for symmetric and non symmetric matrices.
Advanced II edition now supports operations with complex matrices.
The Matrix ActiveX Component delivers all the speed, numerical stability, robustness and scalability you could ask for, significantly reducing development time and allowing you to focus on the actual goals of your application. Without compromising speed, it uses an object-oriented approach to matrix math computation, it provides you with the Matrix and CMatrix Classes containing all the Properties, Methods that you'll need when deploying your numerical exploration. You may be developing a statistical package, or you might want fast 3D graphics transformations, or you may need to solve simultaneous equations, multivariate linear regressions, or to solve EigenValues and EigenVectors problems, Matrix ActiveX Component can do all of this and more.

The program is based on the powerful model-free method of time series analysis Caterpillar (another name is SSA - Singular Spectrum Analysis). It combines advantages of other methods with simplicity of visual control aids. The basic Caterpillar-SSA algorithm for analyzing one-dimensional time series consists of transformation of the one-dimensional time series to the trajectory matrix by means of a delay procedure (this gives the name to the whole technique); Singular Value Decomposition of the trajectory matrix; reconstruction of the original time series based on a number of selected eigenvectors. The result of the Caterpillar-SSA processing is a natural decomposition of the time series into several components, which can often be identified as trends, seasonalities and other oscillatory series, or noise components. The method can be naturally extended to forecasting time series and its components, processing multidimensional time series and to change-point detection. The "Caterpillar" ideas were independently developed in Russia (St. Petersburg, Moscow) and also in UK and USA (under the name of SSA; that is, Singular Spectrum Analysis). The new book "Analysis of Time Series Structure: SSA and Related Techniques", authors are N. Golyandina, V. Nekrutkin and A. Zhigljavsky, provides a careful, lucid description of SSA general theory and methodology (in English, Chapman&Hall/CRC, see http://www.gistatgroup.com/cat/). The method is a powerful and useful tool of time series analysis in meteorology, hydrology, geophysics, climatology and, according to our experience, in economics, biology, physics, medicine and other sciences; that is, where short and long, one-dimensional and multidimensional, stationary and nonstationary, almost deterministic and noisy time series are to be analyzed. We are sure, that in a near future "Caterpillar"-like methods will rank among the base methods of time series analysis and will be included in standard statistical software.

Factorizer is a Windows program to find factors of numbers up to 2,147,483,646 and to find primes, pairs of primes and Palmen colors of numbers.
Or in more detail, Factorizer may be used:
(1) to get the prime decomposition of all numbers in a range of numbers,
(2) to get all factors of a single number or all factors of all numbers in a range,
(3) to find only the prime numbers in a range of numbers,
(4) to find pairs of prime numbers (e.g. 107 and 109) in a certain range,
(5) to count (without displaying) the prime numbers in a range of numbers.
(6) to find Fermat and Mersenne primes < 2,147,483,647
(7) to find the Palmen color of a number or the colors of a range of numbers.
In addition a "filter" condition may be set to allow examination of numbers with a constant offset from an arithmetical or a geometrical progression, e.g., just those numbers of the form 7*n - 12 or 10n + 2.

Full-featured implementation of the de facto industry standard COCOMO 81 (detailed model) software project effort and schedule estimation algorithms, with extensions that also project cost based on development organization labor grade/pay structure. Calculations are based on estimated program size, adjusted for development environment characteristics (complexity, reliability, throughput/memory constraints, etc.). Detailed model supports functional decomposition of program to components that can be more accurately estimated. Attribute factors are applied at all levels of the program structure, allowing best characterization for various differences across the project. SCEP also includes estimates for the reuse of existing modules with modifications.
