function c=batmask()
%BATMASK Load a Gabor multiplier symbol for the 'bat' test signal
% Usage: c=batmask;
%
% BATMASK loads a Gabor multiplier with a 0/1 symbol that masks out
% the main contents of the 'bat' signal. The symbol fits a Gabor
% multiplier with lattice given by a=10 and M=40.
%
% The mask was created manually using a image processing program. The
% mask is symmetric, such that the result will be real valued if the
% multiplier is applied to a real valued signal using a real valued
% window.
