WebNov 29, 2024 · In the event this error is occurring due to a CVX bug, you can try rewriting your code (still using rel_entr) and see whether the error still occurs. For instance, objective = 0; for i = 1:N, objective = objective -rel_entr (... ; end; maximize (objective) . guoxiao_yin November 29, 2024, 2:14pm 3 Hi Mark,Thanks you for your reply. http://cvxr.com/cvx/doc/dcp.html

WebAug 2, 2024 · SUM(ABS(X).^2)./Y if Y is positive, and +Inf otherwise. Y must be real. If X is a matrix, quad_over_lin(X,Y) is a row vector containing the values of quad_over_lin applied to each column. If X is an N-D array, the operation is applied to the first non-singleton dimension of X. quad_over_lin(X,Y,DIM) takes the sum along the dimension DIM of X. WebMar 31, 2024 · Disciplined convex programming information: quad_over_lin is convex, nonmontonic in X, and nonincreasing in Y. Thus when used with CVX expressions, X must be convex (or affine) and Y must be concave (or affine). YANG (Yang) April 1, 2024, 1:14am 3 Thank you very much. The problem is solved.

The use of rel_entr(X,Y) in an objective or constraint will effectively constrain both X and Y to be nonnegative, hence there is no need to add additional constraints X >= 0 or Y >= 0 to enforce this. edleather
