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: Double. 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 zsteqr_(char *compz, integer *n, doublereal *d, doublereal *e, doublecomple x *z, integer *ldz, doublereal *work, integer *info) Details : Fullsource Readme Source Utilities Sites : (1) NETLIB
