Help on zggevx routine

[truelies]

I connected the non symmetry generalized eigenvalue routine to my code, but it can't pass the link. The reason is it can't find some external functions, like following:

* .. External Functions ..
DOUBLE PRECISION DLAMCH
EXTERNAL DLAMCH

The file I downloaded doesn't include dlamch.f. Where can I find this file? Thanks!

When you download an individual LAPACK routine you can choose a link of the form 'zggevx.f plus dependencies' from:

http://www.netlib.org/lapack/complex16/

If you are likely to want to use several LAPACK routines, then it may be better to install all of LAPACK, or to use an existing LAPACK library if your OS has one available.

Finally I got all the routines. Under Intel Fortran it can be compiled and linked. But when I run it, got "array out of bound", the code request B(151,152), but the largest matrix I have is B(151,151). I found a lot of B(*,*) caused this. Did you have this problem before?
