Expert functions

The library provides a set of configuration structures:

• starneig_hessenberg_conf : A configuration structure for Hessenberg reduction related expert interface functions.
• starneig_schur_conf : A configuration structure for Schur reduction related expert interface functions.
• starneig_reorder_conf : A configuration structure for eigenvalue reordering related interface functions.
• starneig_eigenvectors_conf : A configuration structure for eigenvector computation related interface functions.

The default parameters can generated with the following interface functions:

• starneig_hessenberg_init_conf() : Generates default parameters for Hessenberg reduction related expert interface functions.
• starneig_schur_init_conf() : Generates default parameters for Schur reduction related expert interface functions.
• starneig_reorder_init_conf() : Generates default parameters for eigenvalue reordering related interface functions.
• starneig_eigenvectors_init_conf() : Generates default parameters for eigenvector computation related interface functions.

A user is allowed to modify these default values before passing them to the expert interface function.

Only certain interface functions have expert version:

• starneig_SEP_SM_Hessenberg_expert()
• starneig_SEP_SM_Schur_expert()
• starneig_SEP_SM_ReorderSchur_expert()
• starneig_SEP_SM_Eigenvectors_expert()
• starneig_SEP_DM_Hessenberg_expert()
• starneig_SEP_DM_Schur_expert()
• starneig_SEP_DM_ReorderSchur_expert()
• starneig_GEP_SM_Schur_expert()
• starneig_GEP_SM_ReorderSchur_expert()
• starneig_GEP_SM_Eigenvectors_expert()
• starneig_GEP_DM_Schur_expert()
• starneig_GEP_DM_ReorderSchur_expert()
