% PHYS = WFDB_aduphys(SIG_NUM, ADU);
%
% Converts signal value(s) in ADU from A/D units to physical units,
% based on the values of gain and baseline for input signal number SIG_NUM.
%
% SIG_NUM: Signal number (note: the first signal is signal number 0, etc.)
% ADU: Signal values in A/D units (scalar or vector)
% PHYS: Resulting value(s) in physical units
