fsolve - "Not enough input arguments"

Hello all,

Please bear with me, as I'm just learning MATlab. I'm having trouble using fsolve to solve a set of equations. This is what I have so far:

function F = eqns(x)

x0 = [190 130];

%%x(1) is T_roof, x(2) is T_attic%%

F = [-(11079926996490695535*(x(1) + 45967/100)^4)/4835703278458516698824704 + 835*x(2) - (5482846673300357*x(1))/2199023255552; 
        835*x(1) - (36965966212295679*x(2))/35184372088832 + 324703121573247955/17592186044416];

x = fsolve(@eqns,x0);

end

When I try to run the program, I get an error message in the workspace saying that there are not enough input arguments. Any help would be greatly appreciated.

If anyone could give me a hand, I would greatly appreciate it. Thanks! if true

function x = Start
  x0 = [190 130];
  x = fsolve(@eqns,x0);
end

function F = eqns(x)

%%x(1) is T_roof, x(2) is T_attic%%

F = [-(11079926996490695535*(x(1) + 45967/100)^4)/4835703278458516698824704 + 835*x(2) - (5482846673300357*x(1))/2199023255552; 
        835*x(1) - (36965966212295679*x(2))/35184372088832 + 324703121573247955/17592186044416];

end

Store this in Start.m and invoke Start
