function y = rectpuls(t,Tw)
%RECTPULS Sampled aperiodic rectangle generator.
%   RECTPULS(T) generates samples of a continuous, aperiodic,
%   unity-height rectangle at the points specified in array T, centered
%   about T=0.  By default, the rectangle has width 1.  Note that the
%   interval of non-zero amplitude is defined to be open on the right,
%   i.e., RECTPULS(-0.5)=1 while RECTPULS(0.5)=0.
%
%   RECTPULS(T,W) generates a rectangle of width W.

%   See also GAUSPULS, TRIPULS, PULSTRAN.
