CVX subject to express this restriction in CVX: x>0

How to express this restriction in CVX: x>0. If i use x>0, matlab will give warning. Will these warnings affect the final result?
Hope for your solutions.

CVX, and the solvers it calls, will treat struct inequalities as non-strict inequalities.

If you really need a strict inequality, you need to include a buffer quantity, small_positive_number, such as 1e-4 or 1e-5 , and use x >= small_positive_number . If you make small_positive_number smaller than solver feasibility tolerance, you are not guaranteed that the returned solution will satisfy the strict inequality.

Thank you very much. The solution of the problem itself will not get 0, so I can ignore it.
