> Hello Dear all:
> My questions are as follows:
> First I definite a function is f[x_,y_]:=2x+3y
> Then I have a list is data={{1,2,0},{2,3,0},{4,1,0},{6,3,0},{1,3,0}}
> For example{y,x,z}={1,2,0}    {y,x,z}={2,3,0}  {y,x,z}={4,1,0}
> {y,x,z}={6,3,0} {y,x,z}={1,3,0}
> I want to take the list data to the function to get the function
> values.
> Then express the form as follows at last
