% WFDB_setifreq(IFREQ);
%
% Set the input sampling frequency (in samples per second per signal).
% WFDB_setifreq should be invoked after opening the input signals (using
% WFDB_isigopen), and before using any of WFDB_getvec, WFDB_getann,
% WFDB_putann, WFDB_isigsettime, WFDB_isgsettime, WFDB_timstr,
% WFDB_mstimstr, or WFDB_strtim. Note that the operation of WFDB_getframe is
% unaffected by WFDB_setifreq.
%
% Use WFDB_setifreq when your application requires input samples at a specific
% frequency. After invoking WFDB_setifreq, WFDB_getvec resamples the digitized
% signals from the input signals at the desired frequency, and all of the
% WFDB_tools functions that accept or return times in sample intervals
% automatically convert between the actual sampling intervals and those
% corresponding to the desired frequency.
%
% IFREQ: Desired input sampling frequency.
