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

Example:
