applying iterative solutions with Fsolve in multiple variables equations.

hello; have variables in these equations. they are x z and k. And I am trying to solve it with iterative process but I can't find the result for 3 variables. can you help me. where am I doing wrong?

f = @(x,y,k) [busdata(2,2)-...;
              busdata(3,2)-...;
              busdata(3,3)-...];
F = @(p)f(p(1),p(2),p(3));
p0 = [0;0;0];
options = optimoptions('fsolve','Display','iter');
[p,fval] = fsolve(F,p0,options)
