CHETRD.C

 
Reduces a complex Hermitian matrix to real symmetric tridiagonal form by an
unitary similarity transformation. (Computational routine.). [C version of
LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D4c1b1 . Reduce matrix to tridiagonal form
 
Type     : C subroutine in CLAPACK package.
Access   : Public domain. Portable.
Precision: Single.
Note     : For best results, CLAPACK developers prefer that you download and
           install the entire CLAPACK library on your system. To do this, see the 
           netlib CLAPACK distribution for details.
 
Usage    : int chetrd_(char *uplo, integer *n, complex *a, integer *lda, real
           *d, real *e, complex *tau, complex *work, integer *lwork, integer
           *info)
