FindGraph
-
Version
2.54
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 Douglas-Peucker algorithm,
and the empirical mode decomposition (EMD) algorithm
are included. 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.
