Dear Math Group,
How can I get the linear independent subset of a list of symbol, function, and
derivative of functions?
Here is a example:
For {a, b, a+b, c, b-c}, one of the subsets is {a,b,c}. In fact, any one of
the subsets would work for me.
Another example. For {F[x], G[x], D[F,x],D[G,x,2], F[x]+D[F,x],
D[G,x,2]+D[F,x]+F[x]}, the subset would be {F[x], G[x], D[F,x],D[G,x,2]}.
I have went through the help of Mathematica and did find anything like this.
Help is really appreciated.
Liguo
