Hi Akira,

Thanks for pointing this out.  We actually fixed this bug in late January; 
the new code is in the scalapack SVN repository, and will be included in the 
next release.

I agree that a complex version of the parallel QR code would be really nice 
to have.  We have been discussing when and how to get this done, but have no 
definite schedule yet.  Hopefully we will get to it by this summer...

ScaLAPACK team,

Hi, I found a tiny bug in scalapack-2.0.1. In SRC/pblas.h,

line 546: #define crot_ CROT
line 558: #define zrot_ ZROT

should be added to use PCLAHQR and PZLAHQR.
I got an link error when compiling a C++ code with a call to PZLAHQR
on a machine where ScaLAPACK uses BLAS and LAPACK subroutines
have uppercase names. With these lines the code worked fine.

By the way, it would be really nice if PCHSEQR and PZHSEQR would
be implemented.
