Problems and questions encountered when working with matlab

I'm doing a matlab session today and it clearly needs a warm-up.
In almost every m-file I try from the book DAFX, I either don't fully understand it, either it gives errors, either I don't see how it can be used with an audio fragment.
A short google search on "matlab commands functions for digital audio" gives me a few interesting looking URL's:
http://ccrma.stanford.edu/~jos/filters/Matlab_Utilities.html
and further on "audio in matlab":
matlab audio processing examples
http://vise.www.ecn.purdue.edu/VISE/ee438L/matlab/help/pdf/audio.pdf
audio processing


Some questions I have:
  • How do you allow figures to be in one window? And with a title...
  • What must you do when a function used in an example m-file of the book DAFX isn't recognized by matlab? (like CreateNewTrack)

More images in one figure:
I think you can do it with subplot(),stem/plot(),title('');
ButI don't know yet which exact arguments you have to use for that.

For subplot commands see the post above.

1) unicomb uittesten voor toms_diner.wav
- berekentijd veel te lang... moet iets aan gedaan worden...
- na 20 minuten is het eens gelukt...
- werkt wel maar te traag dus

2) vibrato proberen uit te werken
- te veel rekentijd
- slechte parameterkeuze
- nu ok
3) uittesten van wisperization
- boek ligt op kot dus gewoon wa prullen
- effect duidelijk hoorbaar enkel nog te cru
- beetje met parameters experimenteren
en er een bestand van maken waar ge gewoon
wav-file aan kunt meegeven
