WebJan 25, 2024 · Hi there. I am trying to solve a convex problem by CVX toolbox. When I was running my code, the toolbox told me that ‘cannot perform the operation: {positive constant} ./ {real affine}’. The optimization problem is: \… 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.

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. hofman electrical groupWebMay 1, 2015 · You can use the CVX function inv_pos(x), defined as 1/x for x>0 and ∞ otherwise, for the convex portion of 1/x; CVX recognizes this function as convex and nonincreasing. In CVX, you can express the concave portion of 1/x, where x is negative, using -inv_pos(-x), which will be correctly recognized as concave and nonincreasing. huarache 2022WebMar 24, 2024 · That expression should be affine. I opened an issue trace_mpower (matrix,1) returns concave expression instead of affine at the CVXQUAD GitHub site. There really is no point to using CVXQUAD’s trace_mpower with an exponent of 1.

Now consider the second term min(4,1.3-norm(A*x-b)). CVX recognizes that min is concave and increasing, so it can accept concave arguments. CVX recognizes that 1.3-norm(A*x-b) is concave, since it is the difference of a constant and a convex ... huarache 25th anniversaryWebIn CVX, functions are categorized in two attributes: curvature (constant, affine, convex, or concave) and monotonicity (nondecreasing, nonincreasing, or nonmonotonic).
