You use gset to tell Octave how to communicate with the plotting engine. I wanted to plot my graphs to file, but with a dynamic filename. So, <code>gset terminal png; % set the output file format</code> works fine. However: <code>gset output ["graph-" num2str(i) ".png"]; </code> doesn't work. Instead, you need to do: <code>eval(sprintf('gset output "graph-%03d.png"',i))</code> I later had problems with gset. You use gset to tell Octave how to communicate with the plotting engine.

Scilab

n some ways, Scilab may be the “best” of the Matlab clones.

Octave

Like Scilab, Octave is another mature, high-quality Matlab clone. If you use a Unix-like operating system, Octave may be a better choice than Scilab because it reportedly offers better compatibility with Matlab.
