Global Least Squares Analysis : Non-negative Truncated Singular Value Decomposition

New! XPFit - eXPonential Fitting Software : Download

The new advanced XPFit (eXPonential Fitting) package for the analysis of exponential decay curves is the result of our extensive experience in the processing of Fluorescence Analysis and Photon Correlation Spectroscopy data. XPFit performs advanced analysis of superposition of exponentially decaying curves with positive and negative amplitudes. Tools for fitting with up to 4 discrete exponentials or decay times distribution analysis are available. XPFit effectively combines a user friendly, graphical interface with sophisticated mathematical algorithms for solving the associated ill-posed optimization problems. Computational results are exported as image, clipboard or HTML document. More information >>

Global Least Squares Analysis (GLSA) library

GLSA library implements a proprietary algorithm for reliable non-linear least squares data analysis with minimal dependence on initial conditions and minimal probability of being caught into local minima. This is the only commercial, general-purpose library that allows simultaneous fit of several data sets with (optionally) different model functions while some of optimized parameters are linked together. The classical, one data set, one model function fit is implemented as a particular case of a more general multi-model, multi-set problem. The library may be licensed for integration into end-user software products as well as to end-users writing their own data analysis software. More information >>

Non-negative Truncated Singular Value Decomposition (NTSVD) library

NTSVD is a proprietary algorithm for solving ill-conditioned linear least squares problems with non-negativity constraints. The algorithms exploits well-known advantages of Truncated Singular Value Decomposition as a way of stabilization with search of non-negative solution only. The algorithm has proved itself in multiple practical applications and it is available as a software library for integration into end-user software products as well as to end-users writing their own data analysis software.
