# The files here comprise a version of EISPACK that has been tuned to # take advantage of the cache, the vector registers, and the vectorizing # compiler of the IBM 3090-VF. Some of these files were not modified at # all (from the original EISPACK versions), but are included here for # completeness. lib paper for description of changes to eispack by Cline and Meyering lib single prec single by Cline and Meyering lib double prec double by Augustin Dubrulle # Thus to get the file double precision vectorized tql2 subroutine, say # send tql2 from eispack/3090vf/d. # To get the corresponding single precision, say # send tql2 from eispack/3090vf/s. # Because the code contains a few IBM-specific constructions not understood # by the compiler here, netlib can not provide its customary dependency # analysis. So you have to ask for each subroutine individually. For a # list of subroutines, see the index for (standard) eispack. # # Patches posted to the na-digest have been applied to the appropriate # files.
