MathGL: version 2.4.4 (Stable) released

MathGL library makes wide spectrum of mathematical graphics (plots, surfaces, contours, isosurfaces and so on) in platform independent way. Graphics may be exported to EPS, SVG, PNG, JPEG, GIF or IDTF formats. Front-end for library is based on FLTK, Qt and/or GLUT libraries. Also it is possible to draw plot in console regime directly to the file (bitmap, PostScript or SVG) without using X-server. Output graphics is adopted to use with wxWidgets, Qt and other libraries.

New version 2.4.4 contain a number of improvements and bugfixes:

• Add 'minmax' for positions of local maximums and minimums.
• Add ContGen() and ContFGen() to draw contour lines manually. Correspondingly 'cont' and 'contf' commands are extended.
• Add 'conts' for getting coordinate of contour lines.
• Extend 'put' for partial filling if data size(s) are smaller as destination.
• Classes mglFormula and mglFormulaC now can read file with given sizes if string have the format ":fname:x1:x2:y1:y2:z1:z2". Here data is supposed in range [x1,x2][y1,y2][z1,z2] (by default [0,1][0,1][0,1]). Calc() in this case return the interpolated values.
• mglData now have operator() which work as SubData() function.
