D.15.5.3 scheme
Procedure from library finitediff.lib (see finitediff_lib).
- Usage:
- scheme([v1,..,vn]); v1,..,vn of type vector
- Return:
- poly
- Purpose:
- performs substitutions by the means of Groebner basis computation
of the submodule, generated by the input vectors, then intersects the
intermediate result with the suitable component in order to get a finite
difference scheme
- Note:
- works only for a single PDE, for the case of a system use
matrixsystem
