Re: [OctDev] adopting functions from Octave-forge

[Paul K. <pki...@us...>]

Given the minimal time I have for maintaining octave-forge
and in particular, for making sure that it stays in sync with
octave, I propose we delete what we can.

mu2lin and lin2mu: check the octave mailing list for bug
reports.  IIRC the octave-forge version is more compatible
with matlab.

tf2zp and zp2tf: check the octave mailing list for bug
reports.  IIRC there are some cases which fail in octave
but not in octave-forge.

rand, randn, randp, rande: much faster in octave-forge than in
octave, more bits of randomness and longer sequence. poisson_rnd
or whatever it is called now should call randp.

grid: octave-forge allows finer control of the grid such as
the number of tic marks and which axes they are shown for.

detrend: extra/nan and extra/tsa need to be resolved by Alois

chol: check whether octave-forge is faster, and whether it is
enough faster.


Eliminate the following:

polyder, polyderiv, polygcd, sortrows, isequal,cellstr
unique,ismember,setdiff, strcmpi, strmatch, strncmp, print
complex double char full sparse isspace. gammaln,
builtin,dispatch,dispatch_help,
fieldnames, isfield, rmfield,isa

hankel, toeplitz, tril, triu: these were attempts to trade
memory for speed.  I believe the speed gain is only for small
matrices which don't need it.  I think we should turf these.
