org.netlib.lapack.Slapll
public class Slapll
- 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.

* Purpose
* =======
*
* Given two column vectors X and Y, let
*
* A = ( X Y ).
*
* The subroutine first computes the QR factorization of A = Q*R,
* and then computes the SVD of the 2-by-2 upper triangular matrix R.
* The smaller singular value of R is returned in SSMIN, which is used
* as the measurement of the linear dependency of the vectors X and Y.
*
* Arguments
* =========
*
* N (input) INTEGER
* The length of the vectors X and Y.
*
* X (input/output) REAL array,
* dimension (1+(N-1)*INCX)
* On entry, X contains the N-vector X.
* On exit, X is overwritten.
*
* INCX (input) INTEGER
* The increment between successive elements of X. INCX > 0.
*
* Y (input/output) REAL array,
* dimension (1+(N-1)*INCY)
* On entry, Y contains the N-vector Y.
* On exit, Y is overwritten.
*
* INCY (input) INTEGER
* The increment between successive elements of Y. INCY > 0.
*
* SSMIN (output) REAL
* The smallest singular value of the N-by-2 matrix A = ( X Y ).
