Learn more about cvx, bsxfun MATLAB WebApr 1, 2024 · From Proving that quadratic form is convex in (vector, matrix) arguments we know that $$f(Q,x) = x^T Q x$$ is a convex function jointly in $Q$ and $x$ when $Q\succeq 0$. How can I optimize with respect to this in CVX? Supposedly, trace_inv is supposed to be related but I don't see how to use trace_inv to implement a minimization of $f(Q,x)$. WebCVX recognizes that min is concave and nondecreasing, 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 function. So CVX concludes that the second term is also concave. The whole expression is then recognized as concave, since it is the sum of two concave ... dumfries to ayr bus times
