Chapter 3 Preparations for the Investigationmponents may not qualify it as sparse. Moreover, the concept is complicated by the fact that sparsity is not a property of the unknown alone, but of its representation: . is a process of representing the unknown in a suitable basis or frame in terms of few nonzero coefficients.
