.TH analyze 1 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
analyze - frequency plot of a sound  signal
.SH CALLING SEQUENCE
 analyze (w [,fmin,fmax,rate,points])
.fi
.SH PARAMETERS
fmin,fmax,rate,points
: scalars. default values fmin=100,fmax=1500,rate=22050,points=8192;
.SH DESCRIPTION
Make a frequency plot of the signal \fVw\fR with sampling rate \fVrate\fR.
The data must be at least \fVpoints\fR long.
The maximal frequency plotted will be \fVfmax\fR, the minimal \fVfmin\fR.
.SH EXAMPLE
.nf
// 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);
