MATLAB: Fzero of two functions subtracted

Question

I am writing a code for calculating fzero of the subtraction of two functions. Just take a very simple example

fun1 = @(x) x^3;

fun2 = @(x) x^2;

fun = @(x)fun1(x) – fun2(x);

fzero(@(x)fun(x),1)

Always errors were shown, what should be the correct syntax? Could you help me please?

Answer 1

fzero(fun,1);

Best wishes

Torsten.
