labplot  2.8.2
About: LabPlot is an application for plotting and analysis of 2D and 3D functions and data. It is a complete rewrite of LabPlot1 and lacks in the first release a lot of features available in the predecessor. On the other hand, the GUI and the usability is more superior.

This class manages matrix based data (i.e., mathematically a MxN matrix with M rows, N columns). This data is typically used to for 3D plots.

The values of the matrix are stored as generic values. Each column of the matrix is stored in a QVector<T> objects.
