MATLAB: Not Enough Input Arguments in fsolve

not enough input argumentproblem

please help to solve and explain why
function f = fun(x)
f(1) = (x(1)-4)^2 +(x(2)-4)^2 – 5;
f(2) = x(1)^2 + x(2)^2 – 16;
options = optimset('display','off')
x = fsolve(@fun,[2 3.5],options)
X = x(1)
Y = x(2)
>> fun()
Not enough input arguments.
Error in fun (line 2)
f(1) = (x(1)-4)^2 +(x(2)-4)^2 – 5;

Best Answer

function myProblem
 options = optimset('display','off')
 x = fsolve(@fun,[2 3.5],options)
 X = x(1)
 Y = x(2)
    function f = fun(x)
    f(1) = (x(1)-4)^2 +(x(2)-4)^2 - 5;
    f(2) = x(1)^2 + x(2)^2 - 16;
    end
end
Running gives the following result
>> myProblem
x =
    1.8058    3.5692
X =
    1.8058
Y =
    3.5692
