Detailed Description

abstract definition of interface to solve the eigenvalue problem for a double-precision real valued tridiangular matrix

The dimensions of the matrix a (locally ditributed and global), the block-cylic-distribution block size, and the MPI communicators are already known to the object and MUST be set BEFORE with the class method "setup"

Parameters

Parameters

self	class(elpa_t), the ELPA object
d	double real 1d array: the diagonal elements of a matrix defined in setup, on output the eigenvalues in ascending order
e	double real 1d array: the subdiagonal elements of a matrix defined in setup
q	double real matrix: on output contains the eigenvectors
error	integer, optional : error code, which can be queried with elpa_strerr
