Change a variable's value wherever exists
显示 更早的评论
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.
Thanks,
