Incoherence matrix
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". WebIn linear algebra, the restricted isometry property (RIP) characterizes matrices which are nearly orthonormal, at least when operating on sparse vectors. The concept was introduced by Emmanuel Candès and Terence Tao and is used to prove many theorems in the field of compressed sensing. There are no known large matrices with bounded restricted …
