Hello,
Let S be a symbolic expression of a certain number of variables taken
from a particular set of variables. How do I find out the list of the
distinct variables that S depends on?
Suppose {x0,x1,x2,x3,x4,x5,x6,x7,x8,x9} is a set of unknowns and S =
x1 + x3*x4 + x5*x7*x9. I need to find the subset {x1,x3,x4,x5,x7,x9}
on which S depends.
