Changing category to "Octave Forge Package" as remez function is part of signal package rather than core Octave.

The help and online description of the remez function state:

n gives the number of taps in the returned filter

However, the correct description is:

n is the filter order.

and the generated filter length taps = n+1


h = size(remez(8, [0 0.25 0.75 1.0], [ 1 1 0 0 ]))
h =

   9   1
