Hello, I was having a hard time trying to debug a code today, but it turns out the problem came from the function norm itself. The infinity norm of a matrix is not correct in Julia. According to Julia norm(A,Inf) = max(abs.(A)), that is it returns the largest element in abs.(A). (Note: might be wo…

What version of Julia are you using? Looks like things have changed from 0.6 to 1.0. According to the 0.6 docs for the norm function, norm(A,Inf) should give the matrix norm induced by the vector infinity norm, so the maximum row sum of A rather than just the entry with largest absolute value. Howev…
