function meshstruct = vec2mesh (vecstruct,npts)
% VEC2MESH transforms grid points from vector to mesh.
%
% MESHSTRUCT = VEC2MESH(VECSTRUCT,NPTS)
%   transforms the vector variable VECSTRUCT to the mesh structure
%   MESHSTRUCT based on the values of NPTS (numbers of points). The
%   MESHSRTUCT variable can be used in MESH fuction, for instance.
%   VEC2MESH works for 2-dim systems only (NPTS must be a vector of
%   dimension 2).
