Hi there I have a matrix of size 298 x 19. I want to have just one column, so 289x1, but it to be the addition of the row.

So I want to add all the columns to turn it to 298x1.

is this what you need

 q=rand(2,3)    % random matrix 2x3
 out=sum(q,2)  % sum each row so output is just 1 column for each row
