This approach preserves any affine structure of A or $[ A\\mid b ]$, such as Toeplitz or sparse structure, and minimizes a measure of error in the discrete $L_p $ norm, where $p = 1,2,\\,{\\text{or}}\\,\\infty $. It can be considered as a generalization of total least squares and we call it structured total least norm (STLN).<\/jats:p>\n                  <jats:p>The STLN problem is formulated, the algorithm for its solution is presented and analyzed, and computational results that illustrate the algorithm convergence and performance on a variety of structured problems are summarized. For each test problem, the solutions obtained by least squares, total least squares, and STLN with $p = 1,2,\\,{\\text{and}}\\,\\infty $ were compared. These results confirm that the STLN algorithm is an effective method for solving problems where A or b has a special structure or where errors can occur in only some of the elements of A and b.<\/jats:p>","DOI":"10.1137\/s0895479893258802","type":"journal-article","created":{"date-parts":[[2005,2,27]],"date-time":"2005-02-27T07:15:07Z","timestamp":1109488507000},"page":"110-126","source":"Crossref","is-referenced-by-count":152,"title":["Total Least Norm Formulation and Solution for Structured Problems"],"prefix":"10.1137","volume":"17","author":[{"given":"J.
