I have created a function "horzcatna" (see attached). It does the same
thing as horzcat, but the matrices need not have the same number of
rows. To make up the difference, NA values are inserted into the empty
elements.
I created this function to simplify saving data out to files for
plotting in external programs (e.g. gnuplot). If there is interest, I
can revise it to meet Octave standards (texinfo help) and place it in
the appropriate octave-forge package, perhaps "general". I don't think
something comparable exists in Matlab.
Regards,
Jonathan
