LAPACK/ScaLAPACK Development

I have lapack 3.4.0. But I want to call zheev.f to computes all eigenvalues and eigenvectors of a complex Hermitian matrix.

I can't find zheev.f in lapack 3.4.0,

Which version do I have to download so I can call zheev.f, or which subroutine in lapack 3.4.0 I can call to computes complex Hermitian matrix?

Thanks a lot!

You may want to download LAPACK directly from NETLIB. zheev routine is part of any version of LAPACK you download/
http://www.netlib.org/lapack/#_lapack_version_3_4_1 to get the latest LAPACK version.

Thanks, you are right. I do have zheev.f in my lapack.

How should I link it?

Previously, I have following comments in my Makefile:
LIBDIR=/home/user/lapack/
LIBS=-L$(LIBDIR) -llapack -lrefblas -ltmglib

But zheev.f is in SRC file. It seems that I haven't linked SRC file yet.

You need to build the LAPACK library.
if you want to use the Reference BLAS, type

Code: Select all

make blaslib

then to actually build the LAPACK library

Code: Select all

make

to link:

Code: Select all

gfortran prog.f -o prog -L$(LIBDIR) -llapack -lrefblas

I did build lapack library. I typed comment 'make'. And I have liblapack.a, librefblas.a, libtmglib.a.

I also have -L$(LIBDIR) -llapack -lrefblas -ltmglib in my Makefile.

So I can just call zheev.f?

I am a little confused. I have folds: BLAS, lapacke, SRC(contains zheev.f), TESTING etc. in lapack.
And I use comments '-L$(LIBDIR) -llapack -lrefblas -ltmglib' to link 'liblapack.a, librefblas.a, libtmglib.a'.

But which comment tells me that It linked to SRC fold, which has subroutine zheev.f ?

Thanks!
