circulantMatrix is a low storage version, which is intended to be used as a replacement to full or sparse matrix.
For most code, the only change should be one extra line.
A = circulantMatrix(A); %recast A to circulantMatrix class.
circulantMatrix overload most MATLAB standard operators for arrays. For example *, /, etc... The result of the operators is circulantMatrix when possible. inv, det uses fft.
