public class Dsesrt
- 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.

\Name: dsesrt
\Description:
Sort the array X in the order specified by WHICH and optionally
apply the permutation to the columns of the matrix A.
\Usage:
call dsesrt
( WHICH, APPLY, N, X, NA, A, LDA)
\Arguments
WHICH Character*2. (Input)
'LM' -> X is sorted into increasing order of magnitude.
'SM' -> X is sorted into decreasing order of magnitude.
'LA' -> X is sorted into increasing order of algebraic.
'SA' -> X is sorted into decreasing order of algebraic.
APPLY Logical. (Input)
APPLY = .TRUE. -> apply the sorted order to A.
APPLY = .FALSE. -> do not apply the sorted order to A.
N Integer. (INPUT)
Dimension of the array X.
X Double precision array of length N. (INPUT/OUTPUT)
The array to be sorted.
NA Integer. (INPUT)
Number of rows of the matrix A.
A Double precision array of length NA by N. (INPUT/OUTPUT)
LDA Integer. (INPUT)
Leading dimension of A.
