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.

Answer 1

[Torsten]

Your optimization toolbox guide and your MATLAB version are compatible ?

Yes...I went through the documentation from the toolbox help menu.

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..

Answer 4

[Torsten]

As objective function, use

function z = vrosenbrock(x)
z = 100*(x(2) - x(1)^2)^2 + (1 - x(1))^2;
