sym, symfun, and function handle

syms y1(x) y2

y1(x) = x^2      % symfun
y2    = x^2      % sym
y3    = @(x) x^2 % function handle

I am on day 1 of learning symbolic toolbox.

My question is about how to use the functions above appropriately.

My understandings so far:

• Between y1 and y2, I understand that y2 needs sub() to evaluate.
• (Answered somewhere on the forum) y3 has better excute time for numeric substitution

Hello,

In order to better understand the use of these functions, I am sharing the documentation of “sym”, function handles and the documentation link for symbolic Math Toolbox which contain examples to help you get started. Below are the links for the same:
