[Octave-bug-tracker] [bug #40663] scatter and scatter3 terribly slow with real-valued color vector

[José Luis García Pallero]

Follow-up Comment #7, bug #40663 (project octave):

The suggestion if Rik is a good solution:

c_discrete = fix (rows (colormap) / range (c(:)) * (c + abs (min (c(:)))));

But it has the problem that if after the scatter() I call to colormap()
function, the colormap has the range [0 64] instead of the range of the
original data
