Why can't a variable holding an equation be used to make a function handle?

%% Test

syms x

eqn(x) = x^2

func = @(x) eqn

func(2)

[Spencer Kranz]

why won't this return the value 4?

I would simply use matlabFunction() as sir Walter says but maybe you have the follwing in mind:

func = @(x) eqn(x)

[Spencer Kranz]

I just forgot the (x) on the end of eqn. I feel like such an idiot. So much time wasted. ughhh

[Spencer Kranz]

thank you though!

Answer 2

[Walter Roberson]

Use matlabFunction()

[Walter Roberson]

Suppose you were to do

A=1; B=2;
C=A+B;
D = @(A) C

What value would you expect D(0) to have? What value would you expect D(5) to have?

Thank you!
