org.netlib.lapack.Dlarrr
public class Dlarrr
- 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
* =======
*
* Perform tests to decide whether the symmetric tridiagonal matrix T
* warrants expensive computations which guarantee high relative accurac
* in the eigenvalues.
*
* Arguments
* =========
*
* N (input) INTEGER
* The order of the matrix. N > 0.
*
* D (input) DOUBLE PRECISION array, dimension (N)
* The N diagonal elements of the tridiagonal matrix T.
*
* E (input/output) DOUBLE PRECISION array, dimension (N)
* On entry, the first (N-1) entries contain the subdiagonal
* elements of the tridiagonal matrix T; E(N) is set to ZERO.
*
* INFO (output) INTEGER
* INFO = 0(default) : the matrix warrants computations preservi
* relative accuracy.
* INFO = 1 : the matrix warrants computations guarante
* only absolute accuracy.
