Detailed Description

abstract definition of interface to solve double complex eigenvalue problem

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

It is possible to change the behaviour of the method by setting tunable parameters with the class method "set" Parameters

Parameters

self	class(elpa_t), the ELPA object
a	double complex matrix a: defines the problem to solve
ev	double real: on output stores the eigenvalues
q	double complex matrix q: on output stores the eigenvalues

Returns

error integer, optional : error code, which can be queried with elpa_strerr
