POLYOMINO_MONOHEDRAL_MATRIX
Linear System for Polyomino Monohedral Tiling
POLYOMINO_MONOHEDRAL_MATRIX,
a MATLAB library which
is given matrices defining a region R and a polyomino P, and returns
the linear system A*x=b that must be solved for binary solutions x,
that represent possible tilings of the region R by the polyomino P.
A region R is a subset of an MRxNR grid of squares.
A polyomino P is a subset of an MPxNP grid of squares.
Both objects are represented by binary matrices, with the property that
there are no initial or final zero rows or columns.
