## org.netlib.lapack
Class Slangb

    java.lang.Object
      org.netlib.lapack.Slangb

    public class Slangb

extends java.lang.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
     *  =======
     *
     *  SLANGB  returns the value of the one norm,  or the Frobenius norm, or
     *  the  infinity norm,  or the element of  largest absolute value  of an
     *  n by n band matrix  A,  with kl sub-diagonals and ku super-diagonals.
     *
     *  Description
     *  ===========
     *
     *  SLANGB returns the value
     *
     *     SLANGB = ( 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 consistent matrix no
     *
     *  Arguments
     *  =========
     *
     *  NORM    (input) CHARACTER*1
     *          Specifies the value to be returned in SLANGB as described
     *          above.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.  When N = 0, SLANGB is
     *          set to zero.
     *
     *  KL      (input) INTEGER
     *          The number of sub-diagonals of the matrix A.  KL >= 0.
     *
     *  KU      (input) INTEGER
     *          The number of super-diagonals of the matrix A.  KU >= 0.
     *
     *  AB      (input) REAL array, dimension (LDAB,N)
     *          The band matrix A, stored in rows 1 to KL+KU+1.  The j-th
     *          column of A is stored in the j-th column of the array AB as
     *          follows:
     *          AB(ku+1+i-j,j) = A(i,j) for max(1,j-ku)<=i<=min(n,j+kl).
     *
     *  LDAB    (input) INTEGER
     *          The leading dimension of the array AB.  LDAB >= KL+KU+1.
     *
     *  WORK    (workspace) REAL array, dimension (MAX(1,LWORK)),
     *          where LWORK >= N when NORM = 'I'; otherwise, WORK is not
     *          referenced.
