BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-64-13 ENTRY:: January 19, 1996 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Computation of the pseudoinverse of a matrix of unknown rank TYPE:: Technical Report AUTHOR:: Pereyra, Victor AUTHOR:: Rosen, Judah Ben DATE:: September 1964 PAGES:: 30 ABSTRACT:: A program is described which computes the pseudoinverse, and other related quantities, of an m $\times$ n matrix A of unknown rank. The program obtains least square solutions to singular and/or inconsistent linear systems Ax = B, where m $\leq$ n or m > n and the rank of A may be less than min(m,n). A complete description of the programs and its use is given, including computational experience on a variety of problems. NOTES:: [Adminitrivia V1/Prg/19960119] END:: STAN//CS-TR-64-13
