How can I get the objective value and decision variable values for each iteration of a CVX program? Also, can I plot those values for each iteration as the code progress?
I want to know how to obtain and process intermediate results of each iteration of a CVX program
You can not. You will have to content yourself with the final values.
You can look at the solver output displayed at each iteration, but the solver may be solving a different problem than what you entered,due to transformations by CVX.
