Hi everybody !

I have the following problem and I would like to know if someone could give me some hints or something to read related to this.

I'm studying multiple reflections of acoustics waves in a circular room and I'm trying to find the modes of this system. I know (but still have to fully understand how and why) that the solution of this problem is given by the Bessel functions.

I would really like to be able to plot these functions in Matlab or actually have a plot of the modes pattern in the room .

Any ideas of how I could do this ? Any help would be very much appreciated!

Thanks a lot in advance !

P.S: really, if someone could show me the way to plotting the Bessel functions in a 3d space in matlab it would be great !
