            Use CppADCodeGen with CMake FetchContent or ExternalProject
            Asked 2021-Nov-25 at 10:56

            I am not good with CMake, and I cannot find good explanations about how to use its FetchContent functionality. Indeed, most repositories seem to require different treatment, and the rules of such treatment defy my comprehension.

            That said, here is my problem. I would like to use CppADCodeGen in my project using CMake FetchContent. Here is my code:

            QUESTION

            Function to invert Eigen matrix without branching statements for auto differentiation
            Asked 2021-Nov-12 at 10:21

            I need to invert an Eigen matrix (9x9 in my particular case) as a part of code that I want to automatically differentiate using CppAD. For this to succeed the code executing the inversion can not contain any branching like for example if or switch statements. Unfortunately, the inverse function of Eigen contains branching with makes the algorithmic differentiation of CppAD fail.

            Mathematically it should be possible to come up with a formulation that does not need branching for a fixed matrix size that is guaranteed to be invertible. Is that correct?

            Do you know of any library that implements such an inverse without branching?

            In general, it is possible to invert arbitrary large (invertible) matrices without branching, but this gets inefficient for bigger matrices. Eigen only does this for matrices up to size 4x4.

            If you want the derivation of the inverse, just use the identity
