Re: merging functions from octave-forge

[David Bateman]

As requested I'm resending a mail I sent during the period the lists
were down. However, note that I've advanced a little more and so the
contents of tis version of the message has a few more functions ported.

Ok, seeing as there are still a large number of the functions on your
list unconverted I've taken a try and doing some of them.

These all seem to now be treated and removed or disabled in octave-forge

Of those that haven't been converted yet I attach a patch to convert 16
more of them to the octave coding style. After these I see that there
are about 90 entries from this list that are not yet converted, these being

Easy to Port:
 factor isprime primes

Hard to Port:
  brighten contourf convhull convhulln csvread csvwrite del2 delaunay
  delaunay3 delaunayn dlmread dlmwrite drawnow edit ellipj ellipke expm1
  fill fill3 fminbnd funm fzero rat rats

* To port rat/rats need to convert to C++ include in pr-output.cc to
  allow "format rat" to work.

* Combine funm with thfm for trig precision, but how to deal with function
  handles and inline functions?

Unclassified:
  ginput gradient griddata gtext hadamard imread imwrite
  inputname interp1 interp2 interpft intersect
  legend legendre magic mat2str meshc mkpp nchoosek
  nthroot ode23 ode45 optimset orient pareto pascal
  patch pcg pchip pcolor peaks perms pie plot3 polyarea ppval
  psi quadl quiver rosser rref scatter sortrows sound soundsc
  spline stem str2double strtok surf surfc
  text textread tsearch unmkpp view voronoi voronoin
  waitbar wavread wavwrite wilkinson xlsread xmlread xmlwrite
  zoom

Some of these will disappear with th Grapics Handle stuff. Also note
that intersection.m should probably also be depreciated and replaced wih
a version that calls intersect.m.
