Cost: US$59.95 Pricing Details	System: Win98,WinME,WinNT 4.x,WinXP,Windows2000,Windows2003,Windows Vista Starter,Windows Vista Home Basic,Windows Vista Home Premium,Windows Vista Business,Windows Vista Enterprise,Windows Vista Ultimate
FindGraph is a comprehensive graphing, curve fitting, and digitizing tool. FindGraph offers 12 generic fits, including linear regression, logistic functions, fourier approximation, rationals, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300 industry-specific 2D formulas. FindGraph uses the Levenberg - Marquardt non-linear algorithm and the Simplex algorithm to fit data. A built-in Wizard helps to apply different curve fits to discover the model that best describes the data. Peak fitting features are included. There is a feature that applies Singular Spectrum Analysis (SSA) to reconstruct and to forecast data series and to extract cyclic sygnals. The latest version includes an autoregression (ARIMA) model. The software enables you to smooth, interpolate, apply FFT and Wavelet filters, subtract, differentiate, integrate, transform data and curves, and to apply Procrustes analysis. The program comes with 200 built-in common graphing 2D functions support for polar, Cartesian, and parametric equations. A built-in Wizard helps to digitize the data. The program supports OLE automation and can be built-in to other software applications.

MatBasic is a calculating, programming and debugging environment using special high-level programming language designed for solving mathematical problems. MatBasic programming language allows execution of difficult mathematical calculations, involving an exhaustive set of tools for the purpose of creation of algorithmic programs. It also allows a user to abstract his mind from the type of working data which can be either real-valued, or complex numbers, or matrices, or strings, or structures, etc. The MatBasic supports both the text and the graphical data visualization. MatBasic is fast language interpreter and its environment application field is wide: from solving the school problem to executing different engineering and mathematical computations. The MatBasic programming language combines; simplicity of BASIC language, flexibility of high-level languages such as C or Pascal and at the same time turns up to be a powerful calculation tool. By means of a special operating mode, Matbasic it is possible to use as the powerful calculator. Also the MatBasic can be used for educational purpose as a matter of studying the bases of programming and raising algorithmization skills. Matbasic is provide following calculation tools: - Base calculation tools; - Full complex arithmetic's; - Linear algebra and operations. Solving systems of linear equations, eigenvalue problems, and singular value problems. Matrix factorizations (LU, Cholesky, QR, SVD, Schur); - Polynomial problems. Roots of the polynomial. Polynomials multiplication, division and other functions; - Numerically evaluate integral of function; - Solve non-linear system of equations; - Find zero of a function of one variable (solve non-linear equation); - Minimize a function of one and more variables; - Solve initial value problems for ordinary differential equations (stiff and non-stiff); and others.

CurvFit	Optimal Designs Enterprise
Resource Type: Software	Resource Application: Education, Engineering
Cost: US$0	System: Win95,Win98,WinME,WinNT 3.x,WinNT 4.x,Windows2000,WinXP,Windows2003,Windows CE,WinME,Windows Vista Starter,Windows Vista Home Basic,Windows Vista Home Premium,Windows Vista Business,Windows Vista
CurvFit (tm) is a curve fitting program for Windows. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked and/or valleys data. CurvFit is an example of Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values. See comments in EX*.? files for ideas on how to converge via solvers. Equation Calculator and Hardcopy Plot prints are now (6/2005) available.
