Stationnary/Propagative components decomposition of a Longitude/Time signal with Fourier harmonics


Updated 03 Dec 2007

Split the signal S(SPACE,TIME) into its downward/upward space
propagating and stationnary components via a 2D Fourier decomposition.
S is a (SPACE,TIME) matrix. We eventually proceed to a space and/or
time filtering. DT,DX are temporal and space step. PERIOD=[Tmin Tmax]
and WAVELENGTH=[Xmin Xmax] are time and space band-pass filters

I specify S(SPACE TIME) matrix, I get the following error. How should my input S look like?

>> WSEdecomp
??? Input argument "S" is undefined.
