- Mutual_coherence_(linear_algebra) abstract "In linear algebra, the coherence or mutual coherence of a matrix A is defined as the maximum absolute value of the cross-correlations between the columns of A.Formally, let be the columns of the matrix A, which are assumed to be normalized such that The mutual coherence of A is then defined asA lower bound is A deterministic matrix with the mutual coherence almost meeting the lower bound can be constructed by Weil's theorem.The concept was introduced in a slightly less general framework by Donoho and Huo, and has since been used extensively in the field of sparse representations of signals. In particular, it is used as a measure of the ability of suboptimal algorithms such as matching pursuit and basis pursuit to correctly identify the true representation of a sparse signal.".
