+% WAVECUT Extracts a segment of a waveform
+%
+%   [WC] = WAVECUT(WF, STARTP, ENDP) extracts a segment of the waveform WF
+%   starting at position STARTP and ending at position ENDP. The input
+%   waveform WF is assumed to be a vector. STARTP and ENDP should be
+%   numeric values indicating the start and end positions of the desired
+%   segment.
+%
+%   Example:
+%       wf = sin(0:0.01:2*pi);
+%       segment = wavecut(wf, 50, 150);
+%       plot(segment);
+%
+%   See also: other functions that process waveforms.
 wc=wf(round(startp):round(endp));
