[GiNaC-list] variable isolation

[Andrea Monzali]

Good evening everybody,

I'm new to ginac, i read the tutorial but i've a question, if I have an
equation expression, something like

symbol x("x"), y("y");
ex eq = 2*x + 3*x*y - 5*y == 0

is there a method to isolate a single variable, i.e.

cout << isolate(eq, x) << endl;
// x == 5*y*(2 + 3*y)^(-1)
cout << isolate(eq, y) << endl;
// y == 2*x*(5 - 3*x)^(-1)

thanks for all replies..
