WebDec 8, 2024 · While working on an exercise, I stumbled upon the term mutual incoherence of a matrix. Upon googling, I didn't find much information outside of some of its properties, but nowhere any definitions. The only thing I found is the definition of a mutual coherence of a matrix. linear-algebra; Share.
