TOMS358
Singular Value Decomposition of a Complex Matrix

TOMS358 is a FORTRAN90 library which implements ACM TOMS algorithm 358, which computes the singular value decomposition of a complex matrix. The conversion to FORTRAN90 was carried out by Aleksander Schwarzenberg-Czerny.

The text of many ACM TOMS algorithms is available online through ACM: http://www.acm.org/pubs/calgo or NETLIB: http://www.netlib.org/toms/index.html.

Languages:

TOMS358 is available in a FORTRAN77 version and a FORTRAN90 version.

Related Data and Programs:

LAPACK_EXAMPLES, a FORTRAN90 program which demonstrates the use of the LAPACK linear algebra library.

SVD_BASIS, a FORTRAN90 program which computes a reduced basis for a collection of data vectors using the SVD.

TOMS581, a FORTRAN77 library which implements an improved algorithm for computing the singular value decomposition (SVD) of a rectangular matrix; this is ACM TOMS algorithm 581, by Tony Chan.
