how to set Constraints in ‘optimize(Constraints,Objective,options);’ if I don't have any constrains in my problem

[Skye Lu]

I don't have any constrains in my problem, I don't know how to set Constraints in ‘optimize(Constraints,Objective,options);’. 

Constraints = None?

Thanks a lot!

This is my code:

% Define variables

x = sdpvar(N,1);

% Define constraints 

% Define an objective

Objective = (lambda*norm( U(:,iter).*x, 1 )+ 0.5*sum((Dic* x-Output).^2) )

% Set some options for YALMIP and solver

options = sdpsettings('solver','sedumi','verbose',0)

% Solve the problem

sol = optimize(Constraints,Objective,options);

Constraints = [];
