Description
Matlab tools to solve the viscous Taylor Goldstein equation for both instabilities and waves
Fourier-Galerkin method is faster and more accurate than the previous finite-difference version.

nash_data.txt : observational data for demonstration problem
vTG_FG.m : the main subroutine
BaryL.m : auxiliary subroutine
vTG_FGprep.m : auxiliary subroutine (call before vTG_FG)
