I am getting an error message 'not enough input arguments' on running Rosenbrock's function using the optimization tool box solver 'fmincon' solver. How to correct it?

I did the same way as in the optimization toolbox guide.

Your optimization toolbox guide and your MATLAB version are compatible ?

For more help, please show us your exact Rosenbrock function, your exact and full fmincon call, and the exact output that you received.

%unitdisk.m
function [c, ceq] = unitdisk(x)
c = x(1)^2 + x(2)^2 - 1;
ceq = [ ];
end
%vrosenbrock.m
function z=vrosenbrock(x,y)
z=100*(y - x.^2).^2 + (1-x).^2; end
This is what I am getting..

As objective function, use
function z = vrosenbrock(x)
z = 100*(x(2) - x(1)^2)^2 + (1 - x(1))^2;
