Variable is x and y，both of them are scalar.How do I express the multiplication of two convex functions
Please provide how it appears in your model. In the objective or in a constraint?
Also how did you conclude the resulting optimization model is convex? What is your proof of that?
Sorry, I found that I made a mistake. My new function is this. It has been proved in other literatures that it is strictly convex in (0, x0). Can this be represented by CVX?
Assuming a,b,c>0 then it looks convex for all B>=0 e.g.
Thank you very much!
But I should how to expression it？It always shows real*log (convex).
You or someone has to figure out a formulation that is CVX i.e. DCP compliant.
Given the function is convex then it might be possible that such a reformulation exist.
I do not know what it is as I write this.
