[Octave-bug-tracker] [bug #64556] unwrap() does not handle NaN and Inf

[Nicholas Jankowski]

Follow-up Comment #4, bug #64556 (project octave):

as a side note since we're messing with this function, the original part that
gets you d using repmat seems rather slow.  replacing with something like:


    sz(dim) = 1;
    zero_padding = zeros (sz);
    d = cat (dim, zero_padding, -diff (x, 1, dim));


tested about 6-10x faster
