Low-Rank Matrix Fitting

LMaFit是一款MATLAB工具包,用于解决几种类型的矩阵优化问题:包括矩阵补全、稀疏矩阵分离及矩阵压缩感知。对于矩阵补全问题,用户无需设置参数;而稀疏矩阵分离和矩阵压缩感知则需要选择平衡参数。

LMaFit is a MATLAB package that currently solves the following problems

  1. Matrix Complete (MC)
    Find a rank-r matrix U such that Uij ~= Aij, (i,j) in E
  2. Sparse Matrix Separation (SMS)
    Find a rank-r matrix U and a sparse matrix S such that U + S ~= A.
  3. Matrix Compressive Sensing (MCS)
    Find a rank-r matrix U such that L(U) ~= b.

where the matrix A is given either in part as in MC or completely as in SMS, while L in MCS is an “underdetermined” linear operator. In general, we assume that data in A or b contain noise. Currently, we also assume L*L’=I. The matrix completion code does not require users to set any parameter, while the other two codes requires the choice of a balancing parameter.
