WebbFirst of all, format your code (type Ctrl-A then Ctrl-I) in the Matlab editor. Second, add more comments. For example, is m the number of grid squares in the horizontal direction? And explain what each of the multiple for loops is doing. It also looks like you have at least one mistake in indexing.

Webb5 juli 2024 · s = 1:n; s2 = s .^ 2; g = repmat (s2, n, 1); a = g + g'; That, or something very like it, should work. Yep. I tried it. Works fine. Even more matlab-y (although personally I'd avoid this kind of thing): s = (1:n) .^ 2; [x,y] = meshgrid (s,s); a = x + y; Share Cite Follow edited Jul 5, 2024 at 23:41 answered Jul 5, 2024 at 23:24 John Hughes Webb"Find the sum of all the elements in the row.
