I use CVX toolboxs to do lasso estimation, I find that every time when the code runs cvx_begin and cvx_end, there will be a large amount of printed output, like the version, iteration times, pstep, dstep, cputime, gap, status and so on, printing them out leads to larger time cost, since I am running the simulation and hope to run as fast as possible, and do not care about these kinds of output, so is there any way or command to disable these output printing?
