3D plot of the normal modes of a circular membrane with free edges

Plots (3D) the solution of the problem of the vibration of a circular membrane with free edges, generating variations of Chladni figures, oscillating in a senoidal fashion.
The code also prints in the screen the required frequency of oscillation for the required normal modes, for a ~30cm diameter plastic circular plate, based on the zero of its J(01) first derivative (in our case ~54Hz).
