% Linear operators are at the core of many of the most basic algorithms
% for signal and image processing. Matlab's high-level, matrix-based
% language allows us to naturally express many of the underlying matrix
% operations (e.g., computation of matrix-vector products and
% manipulation of matrices) and is thus a powerful platform
