MATLAB: Change a variable’s value wherever exists

Question

I have the following code:

syms a
x = a+1;
a = 2;

However, the value of x is equal to a+1.

Because I put a=2, how can I take the output of x to be equal to 2+1=3?

Thanks

Hello Vasilis,

You need to use subs function to calculate value of symbolic function.

subs(x) as last line will give you value of x for a = 2.
