    • Xiao-Wen Chang, Xiaohu Xie and Tianyang Zhou, MILES: MATLAB package for solving Mixed Integer LEast Squares problems, Version 2.0, October 2011.

      This package provides routines to solve the mixed integer least squares problem min_{x,z}||y-Ax-Bz||_2, where x is a real vector and z is an integer vector and [A,B] has full column rank, including the special case min_{z}||y-Bz||_2
