This post describes in enough detail how to package your Python application in a Debian package.
Asymptote is a powerful command driven graph generator. It produces elegant graphs such as that shown below:
The code required to generate this graph is:
import graph;
size(4inches,0);
real f1(real x) {return (1+x^2);}
real f2(real x) {return (4-x);}
xaxis(“$x$”,LeftTicks,Arrow);
yaxis(“$y$”,RightTicks,Arrow);
draw(“$y=1+x^2$”,graph(f1,-2,1));
dot((1,f1(1)),UnFill);
draw(“$y=4-x$”,graph(f2,1,5),LeftSide,red,Arrow);
dot((1,f2(1)),red);
The MimeTex plugin enables the typesetting of complex mathematical formulas using the TeX syntax. The quadratic equation:
