Webb3 aug. 2024 · Say for example I want to sum each row of matrix A, for values less than 0.5: Theme Copy A = rand (3); B = zeros ( size (A) ); B (A<0.5) = A (A<0.5); row_sum = sum ( B, 2 ); But it feels like I should be able to simplify this, with something like: Theme Copy row_sum = sum ( A (A<0.5), 2 ); WebbYou could use permute to do this, though it's maybe worth noting that you can concatenate matrices regardless of the shape (you might want the cat function to help) Theme Copy x=reshape (1:24,3,4,2); y=permute (x, [3 1 2])
