SIFEL kernel (factorization by math library)

Most of the time in the studied SIFEL application is consumed by a matrix factorization that computes the Schur complement. This routine was manually implemented for sparse symmetric skyline matrix format by the authors of the application. As the factorization is implemented using straightforward math formulas to be easy to read, it is most likely not efficient and not comparable to some established versions implemented in math libraries. For given test cases, the factorization takes more than 90 % of the runtime.
