XPFit performs advanced analysis of superposition of exponentially decaying curves with positive and negative amplitudes. Tools for fitting with up to four 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. Version 1.2.1 features error analysis with confidence intervals definition by exhaustive search.
