These programmes are to demonstrate how to find the frequency structure, 
the multiplexing matrix (T) and the demosaicking matrix (D) for a CFA 
pattern given in a matrix.

The frequency structure and the multiplexing matrix (T) can be used for 
CFA analysis and design.

The demosaicking matrix is the inverse (or pseudo-inverse) of T, which
can be used for CFA demosaicking with Dubois's methods:
