hi!

two questions for the most expert among you:

question 1)

i want to evaluate a function A in a point identified by a number of variables that i have already numerically found from the solution of a sistem (let's say my solutions are S:={B=0.01, C=0.2, D:=0.3} ) but A also depends on another variable (Z) to which i want to assign a value

so i need to write eval(A,S) but also considering Z and it seems that eval(A,{S,Z=1}) doesn't work.

how do i tell maple to compute A considering both the solutions in S and Z=1?

question 2)

Hi guys! This is my first question in this forum. I'm a newuser so forgive me if my questions are really basic.

I wrote a non linear system with a number of unknowns and I want to find solutions for a set of values attached to x.

Let's say x:=[0.1, 0.2, 0.3]

I know I have to redefine x:=i and write a "do" command like

for i in x_   do s(i):=fsolve({independent equations},{unknowns to be numerically found})

and i have three sets of solutions s(0.1), s(0.2) and s(0.3)
