Matlab Usage

File Name: sawtooth_fract32_module.m 
 M=sawtooth_fract32_module(NAME, SR, BLOCKSIZE) 
 Creates a sawtooth generator for use in the Audio Weaver. 
 This module has a single 1 channel output pin with controllable  
 frequency. The output of the module changes instantly when the  
 frequency is updated.  Arguments: 
    NAME - name of the module. 
    SR - sample rate 
    BLOCKSIZE - number of samples per output channel.
