| Description |
The modal functions of an elliptic membrane with fixed edges are expressed as products of angular and radial Mathieu functions with the natural frequencies being found in terms of the zeros of the radial functions. Routines to compute functions ce,se, Mc1 and Ms1 are provided. Mode shapes are presented using either animated surface plots or contour plots. The main driver program and associated functions are explained by using the command 'type contents' in the related workspace. |

MATLAB 7.0.1 (R14SP1)

Assigning a column vector into a row of a matrix works in the MATLAB 7.1, but a user found that my program gave an error in version 6.5. I had to transpose the vector first. The fix was simple. |
