Detailed Description

template<int N>
struct gtsam::MultiplyWithInverse< N >

Functor that implements multiplication of a vector b with the inverse of a matrix A.

The derivatives are inspired by Mike Giles' "An extended collection of matrix derivative results for forward and reverse mode algorithmic differentiation", at https://people.maths.ox.ac.uk/gilesm/files/NA-08-01.pdf
