The XYaupd ARPACK Routines

 In this appendix we exhibit the headers of the three main computational routines dsaupd, dnaupd, and znaupd. Although these codes are nearly identical in structure and usage, there are a number of differences that are problem dependent. Therefore, each is listed separately.

Information on the calling sequence, input and output parameters, storage and data types may be found here. Also, error flags and warnings are listed.
