dependat routine search in lapack for fortran

[utab]

Dear all,

I am new to the list. I was looking for the routines for some symmetric eigenvalue problems. I have read from the manual that SSYEV can do what I want to do (as a first try) but there is a problem with the ssyev.f source file, of course, I have a problem with that :). There are some external function references inside the file I checked from the manual that some of these are auxiliary routines and some are other kinds of routines for computation but the question is that is there a way to find all the dependent files which solve a particular problem or do I have to note them and find them individually which is not so reasonable to me. That is why I dropped by :-)). GAMS can make a research on the database depending on the source code type but if I am not mistaken it is not making a dependency search at the same time? When I note the dependent files and check them, I saw that they also have other dependencies so some kind of infinite loop, not really though :))

Some help is highly appreciated on this problem. Thanks in advance and kind regards,
Umut

Dear Umut,

Have you checked that you do not already have LAPACK available for your machine? It comes with a number of Linux distributions, with Cygwin under Windows and is part of Intel MKL and AMD AMCL.

Otherwise it is probably simplest to build all of LAPACK.

Best wishes,

Sven Hammarling.
