	I sent a copy of this bug report to the help-octave list.  Then I realized I 
should have sent it to the bug-octave list.  Sorry for sending it twice.

                                                  -Mark Esplin

  I am using GNU Octave, version 2.1.34 (i686-pc-linux-gnu).  When I try to 
make a Bartlett window I get the following results:

octave:1> bartlett(10)
error: A(I) = X: X must be a scalar or a matrix with the same size as I
error: evaluating assignment expression near line 44, column 17
error: evaluating if command near line 39, column 3
error: called from `bartlett' in file 
`/usr/local/share/octave/2.1.34/m/signal/bartlett.m'

Removing the transpose from lines 44 and 45 of bartlett.m fixes the problem.  
That is change lines 44 and 45 of octave/2.1.34/m/signal/bartlett.m
from:

    c (1 : n+1) = 2 * (0 : n)' / m;
    c (n+2 : m+1) = 2 - 2 * (n+1 : m)'/m;

to:

    c (1 : n+1) = 2 * (0 : n) / m;
    c (n+2 : m+1) = 2 - 2 * (n+1 : m)/m;
