Is there a name for the other diagonal of a matrix?I'm looking for a definition or name for the diagonal from the lower left to the uper right of a matrix, The diagonal from the upper left to the lower right is identified as "main diagonal". The trace(A) is the sum of the elements along the main diagonal. The question: Is there a name for the diagonal from the Lowerleft to the upperright? Or do you have a reference/resource that might have a name for this diagonal? #2 20091211 02:37:17
Re: Is there a name for the other diagonal of a matrix?I've seen that referred to as the antidiagonal. Not sure how common the usage of that is though. Why did the vector cross the road? It wanted to be normal. #3 20091219 11:16:18
