kpl is a program for two-dimensional graphical presentation of data
sets and functions. Nonlinear parameter fits of functions to data sets
can be performed using the Levenberg-Marquardt algorithm. Also general
linear least square parameter fits are possible.
All settings necessary for a complete description of the presentation
can be saved in plot files. These files as well as data files may be
chosen by command line parameters, using the File menu, or by drag and
drop.
Automatic scaling and normalization allow the easy graphical presentation
of data. Also parameter fits can be performed automatically.
The settings of a presentation may be changed using the Edit menu. Here
also additional data sets and functions can be included which
can be displayed in the same as well as in different data windows.
