This is a known bug that was fixed in Octave 3.2.3.. See the thread

http://octave.1599824.n4.nabble.com/Re-OctDev-incorrect-complex-matrix-multiplication-results-in-Octave-3-2-2-td1673571.htm
and

http://octave.1599824.n4.nabble.com/Re-OctDev-incorrect-complex-matrix-multiplication-results-in-Octave-3-2-2-td1673573.html

and the changeset to the 3.2 releases

http://hg.tw-math.de/release-3-2-x/rev/4963bb455582

I'm closing this bug as the issue has been addressed.

Your sample code produces the same result as Matlab on a recent development version of the code.

Could you test a newer release of Octave such as 3.2.4 or compile directly from the Mercurial sources and report back.

Hi,

I found the following compatibility issue.

The result of scalar product between complex row vectors or between complex column vectors in octave is the complex conjugate of the matlab result.
for instance the following instructions
in octave give the result
but in matlabe give
The same holds using column vectors and a*b'

Is it something I get wrong or a bug?

Thank you
