Iteration number of successive approximation

I’ve solved my GGP problem with CXV. I’m wondering if the iteration number of successive approximation can be obtained
throught a variable (cvx_status briefly report “solved”)

No, it cannot, I’m afraid.

An inelegant way of doing this would be to use the MATLAB diary command. Then extract the number of iterations from the diary file, for example using a PERL script invoked from a MATLAB system call, and read in the result into MATLAB and assign it to a MATLAB variable.
