analyze           Scilab Group           Scilab Function            analyze
NAME
   analyze - frequency plot of a sound  signal
  
CALLING SEQUENCE
    analyze (w [,fmin,fmax,rate,points])
  
PARAMETERS
   fmin,fmax,rate,points : scalars. default values
  fmin=100,fmax=1500,rate=22050,points=8192;
  
DESCRIPTION
   Make a frequency plot of the signal w with sampling rate rate. The data
  must be at least points long. The maximal frequency plotted will be fmax,
  the minimal fmin.
  
EXAMPLE
 // At first we create 0.5 seconds of sound parameters.
 t=soundsec(0.5);
 // Then we generate the sound.
 s=sin(440*t)+sin(220*t)/2+sin(880*t)/2;
 [nr,nc]=size(t);
 s(nc/2:nc)=sin(330*t(nc/2:nc));
 analyze(s);
