Question about flux vector splitting details
 

Hello guys,

I recently read papers on weno, where flux splitting tech was used. One of the important step is to construct Jacobians of flux.

I checked the right- and left- eigenvectors in some papers with matlab. The two are reciprocal with each other, however, the published matrix are always different to those obtained by matlab.

My question is, can I use the ones by matlab, or are there any tricks to produce the right and left eigenvectors' matrix?

Thank you very much.
