SSYEVX.C

 
Computes selected eigenvalues and eigenvectors of a real symmetric matrix.
(Expert driver.). [C version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D4a1 . Real symmetric matrix eigenvalue problems
 
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 ssyevx_(char *jobz, char *range, char *uplo, integer *n, real
