I do some revisions to my equation but I still got no answer. It says that there is no enough input argument. Can someone please help me?

function f=rle(x)
f(1)=x(2)+x(3)+x(5)+x(7)-2758.6474;
f(2)=2*x(1) + 2*x(4) + 4*x(5)-5684.5402;
f(3)=x(2) +2*x(3)+x(4)-4292.1525;
f(4)=2*x(6)-6422.3564;
f(5)=((x(1)^3)*(x(2))/(x(4)*x(5)))-(1893.12055);
f(6)=(x(1)*x(3))/(x(2)*x(4))-(0.7631343);
f(7)=((x(1)*x(2))/x(4))-(32.200985);
>> x0=[150;150;150;150;150;150;150];
x=fsolve(rle,x0);
Not enough input arguments.
Error in rle (line 2)
f(x)=x(2)+x(3)+x(5)+x(7)-2758.6474;

x0=[150;150;150;150;150;150;150];
% x = 1:7; % give input vector to fucntion
sol=fsolve(@rle,x0) % call the function using function handle
plot(sol)
function f=rle(x)
f(1)=x(2)+x(3)+x(5)+x(7)-2758.6474;
f(2)=2*x(1) + 2*x(4) + 4*x(5)-5684.5402;
f(3)=x(2) +2*x(3)+x(4)-4292.1525;
f(4)=2*x(6)-6422.3564;
f(5)=((x(1)^3)*(x(2))/(x(4)*x(5)))-(1893.12055);
f(6)=(x(1)*x(3))/(x(2)*x(4))-(0.7631343);
f(7)=((x(1)*x(2))/x(4))-(32.200985);
end
