This is the implementation of the AMIPS energy function of a triangle mesh that can be embedded in 2d or 3d.
It uses autodiff encoding for differentiations.

This function defines a function f(x) where f is defined over a simplex domain and the variables for f are the n vertices coordinates of the simplex.
The input coordinates are obtained through the get_coordinates function. They are encoded in autodiff type so that the function can be differentiated through autodiff.
