Why does matlab's quadratic programming toolbox output specific iteration information every 5 steps

This is my code, and deltaU0 is initial value，I would like to get the result of each iteration of the quadratic programming active set method and store it in the workspace. But now it prints on the command line and it prints the iteration info every five steps instead of every step.

options = optimoptions('quadprog','Algorithm','active-set','Display','iter-detailed');
[deltaU,fval,exitflag,output]=quadprog(W,f,G,g,[],[],[],[],deltaU0,options);

Here is a screenshot of the output from the command line。

We can't run the code without W,f,G,g,deltaU0.

Hello friends, let me add W,f,G,g,deltaU0. In the uploaded attachment, g is replaced by gg
