Can somebody explain me the name and/or intuition behind this equation?
dm(A,B)=max{∥(A−B)x∥:x∈Rn,∥x∥=1}
Kindly refer the equation here: Distance/Similarity between two matrices
EDIT: I posted it here as I didn't have enough reputation to comment and ask in the above question link. Thus, kindly vote the question if possible.
