Problem with recent change to isvector and isscalar

The recent change that Bill made to the isvector and isscalar functions
causes a number of failed tests in the test suite. Perhaps it is the
test that is now wrong and not Bill's changes, but I find that the code

s.a = 1; isvector(s)
ans = 1

rather strange and counter-intutitive behavior. I checked matlab and it
too returns 1 in this case. Can we change the sense of the related tests?

Regards
David

Actually I think Matlab views something as a 1x1 matrix. So the above
struct should be a 1x1 matrix of struct type, thus it is a vector.
Strange, but makes sense somehow.

Yes, we should fix the tests in this case.

problems configuring octave-forge

Re: Problem with recent change to isvector and isscalar

Just 2 euro cent vote in favor of the new behavior. A scalar _is_ a special case of a vector. Making 
the tests conform with mathematical definitions is important to help people program in an intuitive 
manner. If people want to know whether or not something is in  R1, they can check that with "length".

Re: problems configuring octave-forge

This is an error in your octave configuration.

Also, Octave 2.1.50 is several years old and is no longer supported
though you can use an older release of octave-forge available on
the sourceforge download site.

question on octave

Dear listmembers,
when trying to build octave-2.1.73 on cygwin it compiles successful but never starts.
I always get "Aborted (core dumped).
A call with strace is attached so you (might ...) understand what is going on.
gcc --version says 3.4.4;

within rpm the following options are activated:
CXXFLAGS="$RPM_OPT_FLAGS -D_GNU_SOURCE -fno-strict-aliasing" \
        ./configure \
        --prefix=%{_prefix} \
        --exec-prefix=%{_prefix} \
        --libexecdir=%{_libdir} \ 
        --libdir=%{_libdir} \
        --infodir=%{_infodir} \
        --mandir=%{_mandir} \  
        --enable-shared \
        --enable-rpath \ 
        --disable-static \
        --enable-dl \         
        --enable-lite-kernel

Many thanks for helping,
take care

I think this is your problem.  See for example this thread:

  http://www.cygwin.com/ml/cygwin/2005-10/msg00051.html

One solution is to compile with gcc 3.3, the same as the Cygwin
package of Octave does.

AW: question on octave

Dear listmembers, dear Mr. Eaton,
thank you for giving me this pointer; when trying to download the g++ sources I found out that some friendly
soul readily provided a 2.1.73-version of octave for cygwin, therefore I have stopped investigating further,
thanks again,
take care
