non linear equation "problem with not enough arguments"

Im wriitng this to verify my non-linear equations..but having problem with this problem :

"nlinearval

Error using nlinearval (line 14)
Not enough input arguments.
 
 function F=nlinearval(z)
 

Can anyone help me how i can solve this problem? Below are my coding:

function F=nlinearval(z)
%define constants
Isc=8.53;
Voc=44.9;
Vmp=36.1;
Imp=8.04;
Ns=72;
dv_di_oc=-0.48766;
di_dv_sc=-2.48797e-3;
q=1.6e-19;
k=1.381e-23;
T=298;

x = z(1);
y = z(2);
w= z(3);

Rsh = -1/(di_dv_sc);
b=exp(q*((Vmp+Imp*w)/(Ns*y*k*T)));
c=exp((Voc*q)/(Ns*y*k*T));
F(1)=[x-((Isc-(Voc/Rsh))/(c-1))-0];
F(2)=Imp-Isc+x*b+((Vm+Imp*w)/(Rsh));
F(3)=w+dv_di_oc+(1/((x*q)/((Ns*y*k*T)*c)));
end
