how to assign values to a large array of symbolic variables in matlab ?

Hi, I want to assign values to symbolic array let values of V=[5 4 5 2 .....4] to X=[x1 x2 x3 .... xn]. as I can get the result like this x1=5, x2=4 and so on.

Can anyone guide me? Thanks in Advance

You should read this:

And then use subs with a vector (this being the efficient, recommended way to use MATLAB).

This is possible but firmly recommended against. In nearly any context you are likely to encounter, it is better to subs() the values rather than assign them.

if i use X = sym('x',[1 3]) then how can I assign values to each value of X

[Walter Roberson]

Don't. Create a vector with the values and subs(expression, X, values) as needed.

How can I do this?

[Walter Roberson]

X = sym('x', [1,3])
Y = X(1)/5 + cos(X(2))^X(3)
XV = [26, pi/11, 3]
Ynew = subs(Y, X, XV)
