Hi Matthias,
The problem here was that the expression template machinery used by arrays
is separate from that used by vector types, and they are somewhat out of
sync.
In the blitz cvs repository, I have added to the generated header file
<blitz/vecuops.cc>
support for the conj() function. You can now use conj() on all
vector-like types
including TinyVector. Note that in your example program below, you
should be
including the header <blitz/tinyvec-et.h> in order to get the headers
for TinyVector
expression template support. This is no longer included by default by
<blitz/array.h>.
Regards, Julian C.
