1. why its showing "Error using pvcurve (line 15) Not enough input arguments,Error in thesis (line 15) x= fsolve(pvc​urve,Ipv0)​;"?????

FUNCTION CODE IS:
function F = pvcurve(Ipv)
Vpv=0.9;

global Np Ns Isc q T k Io n  
Np = 1; 
Ns=72; 
Isc =1.82;
q= 1.6e-19; 
T=298;
k=1.38e-23; 
Io= 1.2987e-4; 
n=1.8405;
    F = -(Ipv)+ (Np*Isc)- Np*Io*((exp((q*Vpv)/(n*k*T*Ns))-1));

AND MAIN CODE IS :

clc 
clear all
Vpv=0.9;
 Ipv0 = 1;
global Np Ns Isc q T k Io n  
Np = 1; 
Ns=72; 
Isc =1.82;
q= 1.6e-19; 
T=298;
k=1.38e-23; 
Io= 1.2987e-4; 
n=1.8405;
 x= fsolve(pvcurve,Ipv0);
