public class SLASET
extends java.lang.Object

SLASET is a simplified interface to the JLAPACK routine slaset.
This interface converts Java-style 2D row-major arrays into
the 1D column-major linearized arrays expected by the lower
level JLAPACK routines.  Using this interface also allows you
to omit offset and leading dimension arguments.  However, because
of these conversions, these routines will be slower than the low
level ones.  Following is the description from the original Fortran
source.  Contact seymour@cs.utk.edu with any questions.

 *  Purpose
 *  =======
 *
 *  SLASET initializes an m-by-n matrix A to BETA on the diagonal and
 *  ALPHA on the offdiagonals.
 *
 *  Arguments
 *  =========
 *
 *  UPLO    (input) CHARACTER*1
 *          Specifies the part of the matrix A to be set.
 *          = 'U':      Upper triangular part is set; the strictly lower

 *                      triangular part of A is not changed.
 *          = 'L':      Lower triangular part is set; the strictly upper

 *                      triangular part of A is not changed.
 *          Otherwise:  All of the matrix A is set.
 *
 *  M       (input) INTEGER
 *          The number of rows of the matrix A.  M >= 0.
 *
 *  N       (input) INTEGER
 *          The number of columns of the matrix A.  N >= 0.
 *
 *  ALPHA   (input) REAL
 *          The constant to which the offdiagonal elements are to be set.
 *
 *  BETA    (input) REAL
 *          The constant to which the diagonal elements are to be set.
 *
 *  A       (input/output) REAL array, dimension (LDA,N)
 *          On exit, the leading m-by-n submatrix of A is set as follows:
 *
 *          if UPLO = 'U', A(i,j) = ALPHA, 1<=i<=j-1, 1<=j<=n,
 *          if UPLO = 'L', A(i,j) = ALPHA, j+1<=i<=m, 1<=j<=n,
 *          otherwise,     A(i,j) = ALPHA, 1<=i<=m, 1<=j<=n, i.ne.j,
 *
 *          and, for all UPLO, A(i,i) = BETA, 1<=i<=min(m,n).
 *
 *  LDA     (input) INTEGER
 *          The leading dimension of the array A.  LDA >= max(1,M).
