6. mglData class

Class for working with data array. This class is defined in #include <mgl/mgl_data.h>. The class has functions for easy and safe allocation, resizing, loading and saving, modifying of data arrays. Also it can numerically differentiate and integrate data, interpolate, fill data by formula and so on. Class supports data with dimensions up to 3 (like function of 3 variables – x,y,z). The internal representation of numbers is float. Float type was chosen because it has smaller size in memory and usually it has enough precision in plotting purposes. You can change it by selecting option --enable-double at the library configuring (see section Installation and usage).
