Matlab: finding largest sum of first dimension, grouping by second dimension?

Since your question isn't super clear and I don't get what sum you are referring to I'm just gonna guess that you are aiming for something like this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
