Hi all, I’m working on a parameter estimation problem of an ODE system with two variables u1 and u2. As one part of an objective that I will use in the loss function, I want to calculate a vector of the product of combinations with repetitions of u1 and u2 . For example, I want v where v = [[u1 .*…

[image] vleon1234: Tullio looks promising! Unfortunately, I tried implementing and ran into another with how I’m using Tullio, since there is no gradient definition for a Vector of a Vector. Is there a good way to get around this? Reduce that to a matrix?
