How do I limit the optimization variable to be non-negative when I'm using the sedumi solver

[Mark_L_Stone]

Do both of the following:

1. We don’t know what your input data is. You should rescale the data (variables) if not all non-zero input data are within a small number of orders of magnitude of one.

2. If Mosek is available to you, use it as solver. Otherwise follow the advice at CVXQUAD: How to use CVXQUAD's Pade Approximant instead of CVX's unreliable Successive Approximation for GP mode, log, exp, entr, rel_entr, kl_div, log_det, det_rootn, exponential cone.
