Symbolic function for a vector

Question

I want to define a symbolic vector in Matlab, but every element of the vector should be created through a symbolic function.

Let's say f(x)=x^2 is my function and I have a vector A=[1 2 3 4 5]. I want to create a symbolic vector so that it is going to be like this;

Symbolic_vector=[x^2 2*x^2 3*x^2 4*x^2 5*x^2]

How can I realize this ?

So far I have

A=[1 2 3 4 5];
syms x;   
m = sym('m', [1 100]);                                             
f = sym('x^2*m');
f = subs(f, m, A);

Answer 1

One way to do this and keep things symbolic is

A = sym('[1 2 3 a 5]');
f = @(x) x.^2;
B = f(A);

% results in B = [1 4 9 a^2 25]

You can also do directly

B = A.^2;

Answer 2

syms a;

A = [1 2 3 a 5];

B = A.^2;

I hope this helps.
