public class Dlansy

extends Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.
Contact seymour@cs.utk.edu with any questions.

 *     ..
 *
 *  Purpose
 *  =======
 *
 *  DLANSY  returns the value of the one norm,  or the Frobenius norm, or
 *  the  infinity norm,  or the  element of  largest absolute value  of a
 *  real symmetric matrix A.
 *
 *  Description
 *  ===========
 *
 *  DLANSY returns the value
 *
 *     DLANSY = ( max(abs(A(i,j))), NORM = 'M' or 'm'
 *              (
 *              ( norm1(A),         NORM = '1', 'O' or 'o'
 *              (
 *              ( normI(A),         NORM = 'I' or 'i'
 *              (
 *              ( normF(A),         NORM = 'F', 'f', 'E' or 'e'
 *
 *  where  norm1  denotes the  one norm of a matrix (maximum column sum),
 *  normI  denotes the  infinity norm  of a matrix  (maximum row sum) and
 *  normF  denotes the  Frobenius norm of a matrix (square root of sum of
 *  squares).  Note that  max(abs(A(i,j)))  is not a  matrix norm.
 *
 *  Arguments
 *  =========
 *
 *  NORM    (input) CHARACTER*1
 *          Specifies the value to be returned in DLANSY as described
 *          above.
 *
 *  UPLO    (input) CHARACTER*1
 *          Specifies whether the upper or lower triangular part of the
 *          symmetric matrix A is to be referenced.
 *          = 'U':  Upper triangular part of A is referenced
 *          = 'L':  Lower triangular part of A is referenced
 *
 *  N       (input) INTEGER
 *          The order of the matrix A.  N >= 0.  When N = 0, DLANSY is
 *          set to zero.
 *
 *  A       (input) DOUBLE PRECISION array, dimension (LDA,N)
 *          The symmetric matrix A.  If UPLO = 'U', the leading n by n
 *          upper triangular part of A contains the upper triangular part
 *          of the matrix A, and the strictly lower triangular part of A
 *          is not referenced.  If UPLO = 'L', the leading n by n lower
 *          triangular part of A contains the lower triangular part of
 *          the matrix A, and the strictly upper triangular part of A is
 *          not referenced.
 *
 *  LDA     (input) INTEGER
 *          The leading dimension of the array A.  LDA >= max(N,1).
 *
 *  WORK    (workspace) DOUBLE PRECISION array, dimension (LWORK),
 *          where LWORK >= N when NORM = 'I' or '1' or 'O'; otherwise,
 *          WORK is not referenced.
 *
 * =====================================================================
