GEW dispersion script 
Script to compute guided waves in plates.
Extremely fast and robust computation of guided elastodynamic waves (GEWs) in plates. Select between Lamb waves, SH waves or coupled polarization. Easily computes the complex wavenumber dispersion curves. The script implements the spectral collocation method (SCM) based on DMSUITE.
[!TIP] This is a simple script that should be easy to extend with custom functionality. If you are rather looking for a full system to compute and postprocess guided elastic waves, have a look at GEWtool.
Features: - only ~50 lines of Matlab code - does not miss solutions, super fast - general anisotropy - possible to include dissipation - Lamb/SH/coupled polarization - complex wavenumbers
