CSTEQR.C

 
Computes all eigenvalues and eigenvectors of a real symmetric tridiagonal
matrix, using the implicit QL or QR algorithm. (Computational routine.). [C
version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D4a5 .  Tridiagonal matrix eigenvalue problems
            D4a3 .  Complex Hermitian matrix eigenvalue problems
            D4c2a . Compute eigenvalues of tridiagonal matrix
 
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 csteqr_(char *compz, integer *n, real *d, real *e, complex *z,
           integer *ldz , real *work, integer *info)
