Incoherence matrix
Web2 Answers Sorted by: 25 An underdetermined system is one with fewer equations than unknowns, so we can write this as a matrix equation A x = b with A a matrix that has fewer rows than columns. This implies that solutions, if they exist, will not be unique. Two ways to see this: Method 1. WebJan 29, 2016 · Since the coherence equation that you provided depends upon dot-products, the amplitude scaling of your matrix will effect the result. Most likely the equation you provided assumes the matrices are scaled in amplitude. For example, each column in matrixA & matrixB might need to be scaled by it's "Euclidean Norm" or "L2-Norm".

WebDec 8, 2024 · The mutual coherence of a matrix, defined as the maximum absolute value of the normalized inner-products between different columns, is an important property that characterizes the similarity between different matrix columns. Redundant matrices with very low mutual coherence are referred to as incoherent redundant matrices which play an … Webproposed algorithm for two scenarios: matrix completion under Assumption 1, and matrix comple-tion under both Assumption 1 and Assumption 2. Furthermore, we will assume that Assumption 1 always holds, and that the rank k, the condition number ˙ 1 =˙ k, and the incoherence parameter 0 of the matrix Mare bounded from above by a constant, as n!1.
