AB - <p style="text-align: justify;">Hexagonal grid methods are valuable in two-dimensional applications
 involving Laplacian. The methods are investigated on problems related to standard and anisotropic Laplacian using
 Fourier vectors in pure, mixed and combination types. Complete (positive) eigenvalues and eigenvectors are determined
 explicitly in terms of various bases in a unified structure. This work is the smallest completion of some previous works.</p>
