analyze - frequency plot of a sound signal

### 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` .

### Examples

    // 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);
