![]() ![]() More generic data analysis programs with spread-sheet capabilities include the proprietary Origin and its clones QtiPlot (paid, closed source) and SciDAVis (non-paid, open source). The programs LabPlot, MagicPlot and peak-o-mat have similar scope. Column 0 means index of the point: 0 for the first point, 1 for the second, etc. xcol, ycol, scol (supported only in text and CSV files) are columns corresponding to x, y and std. automation of common tasks with scripts. dataslot should be replaced with 0, unless many datasets are to be used simultaneously (for details see: Working with Multiple Datasets).Originally, Fityk was developed to analyse powder diffraction data. ![]() Sometimes alternative methods find global minimum when the L-M algorithm is stuck in a local minimum, but in majority of cases the default L-M method is superior. These methods are slower, some of them are orders of magnitude slower. It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. Fityk can also use a few general-purpose optimization methods.
