Function: 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.
