analyze(1)                     Scilab Function                     analyze(1)
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);
