Remove help message from quadprog() function

Someone knows how I remove the help message when the quadprog function is used?

The message is:

"Solution found during presolve.

Some combination of the bounds, linear constraints, and linear terms in the objective function immediately lead to the solution.

Minimum found that satisfies the constraints.

Optimization completed because the objective function is non-decreasing in feasible directions, to within the default value of the function tolerance, and constraints are satisfied to within the default value of the constraint tolerance.

criteria details"

Thanks

You can call it like this:

 options =  optimoptions('Display','off');
 x = quadprog(H,f,A,b,Aeq,beq,lb,ub,x0,options);

This should disable the output when the solver completes.

Thanks, but it doesn't work. I've put that. It is a kind of help message (blue color, for default), according the Matlab.

This is a sample of the code:

H=[0.0388,0;0,0.1157];

f=[78.5000;95.6400];

A=[1,0;-1,0;0,1;0,-1];

b=[400; -100; 200; -50];

Aeq=[1,1];

beq=300;

lb=[];

ub=[];

x0=[];

[x,fval,exitflag,output,lambda]= quadprog(H,f,A,b,Aeq,beq,lb,ub,x0,'Algorithm','interior-point-convex','Display','off');

You're not calling an options object:

 H=[0.0388,0;0,0.1157];
f=[78.5000;95.6400];
A=[1,0;-1,0;0,1;0,-1];
b=[400; -100; 200; -50];
Aeq=[1,1];
beq=300;
lb=[];
ub=[];
x0=[];
options = optimset('Display', 'off');
[x,fval,exitflag,output,lambda]= quadprog(H,f,A,b,Aeq,beq,lb,ub,x0,options);

This code evaluates for me just fine without any message or warning being displayed.

I know this post is old by now, but

options = optimoptions('Display','off');

produces an error. As you have commented further down, jgg, the correct call is:

options = optimset('Display', 'off');

This works like a charm!
