c@0: function wavwrite(y,varargin)
c@0: %WAVWRITE Write an audio file
c@0: % 
c@0: %   WAVWRITE is a wrapper function for audiowrite, using the same function
c@0: %   name and input arguments as the deprecated MATLAB WAVWRITE function. It
c@0: %   is provided in order to improve the compatibility of legacy code.
c@0: % 
c@0: %   WAVWRITE(Y,FILENAME) writes an audio file specified by the string
c@0: %   FILENAME. The audio data in Y should be arranged with one channel per
c@0: %   column. The data are assumed to be sampled at 8000 Hz and 16 bits per
c@0: %   sample.
c@0: % 
c@0: %   WAVWRITE(Y,FS,FILENAME) specifies the sample rate FS, in Hertz, of the
c@0: %   data.
c@0: % 
c@0: %   WAVWRITE(Y,FS,N,FILENAME) forces an N-bit file format to be written,
c@0: %   where N <= 32.
