What is the problem here to run this code? Can I run this code without using fsolve?

function fn=ex_sys_n(x);
fn(1)=exp(-x(1)+x(2))-x(1)^2;
fn(2)=sin(x(1))+cos(x(2));
clc; clear all; 
fun=@(x) ex_sys_nl(x);
x0=[0,0];
x=fsolve(fn,x0)

x0=[0,0];
x=fsolve(@ex_sys_n,x0)

Equation solved.

fsolve completed because the vector of function values is near zero
as measured by the value of the function tolerance, and
the problem appears regular as measured by the gradient.

x = 1×2

0.3283 -1.8991

function fn=ex_sys_n(x);
 fn(1)=exp(-x(1)+x(2))-x(1)^2;
 fn(2)=sin(x(1))+cos(x(2));
end

Still, it is showing the same error. What should I correct?
