What is this repo?

This is a repo for Julia implementation of Maxvol-related algorithms.

What is Maxvol?

Maxvol is an algorithm which finds a submatrix of quasi-maximum volume in a given matrix. Submatrices of maximum volume play crucial role in low-rank cross (interpolative) approximations as well as in different optimization problems. More on this can be found in the following literature:
