performing iterations until equation becomes zero

i have to perform the iterations for equations,here i gave for the values N starting 0.1 upto 5 .i have to perform iterations until the sold equation becomes to zero.I am not getting any errors,but i am getting wrong values.can anyone help me ??

for i=0.1:0.1:5
    i=N;

No=(Ns+R*N(i))/(1+R);
Nstar=N(i)/(1000*Kn);
jstar=(((sqrt((Lstar^1.76)+(5.2*(Nstar(i)-Nstar_min)))-(Lstar^0.88))/2.6)^1.136);
J=(jstar*(sqrt(Kn*k*Xf*Df)));
X =((bt*Qo*(1+R)*Xo)+(Y*1000*a*V*J*bs))/(bt*((Qo*(1+R))-((V*Y*k*N(i))/((Kn*1000)+N(i)))+V*kd));
sold=Qo*(1+R)*(No-N(i))-V*((a*J*1000)+((X*k*N(i))/((Kn*1000)+N(i))))
end

Shouldn;t your first few lines here be:

N = 0.1:0.1:5;
for i=1:numel(N)
   

No=(Ns+R*N(i))/(1+R);
...etc

thank you
