The following Matlab project contains the source code and Matlab examples used for example of weno3 lf and weno5 lf scheme for 1d buckey leverett problem. Since the WENO scheme uses all the candidate stencils, a clever choice of weights [5] results in a WENO scheme which is of order 2r1 in smooth regions [8]. WENO scheme was constructed for the third order nite volume version based on ENO (Essentially Non-oscillatory) scheme [30]. In 1996, third and fifth order finite difference WENO schemes in multi space dimensions are constructed by Jiang and Shu, with a general framework for the design of smoothness .
