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.

Sum along dimension 2 (columns):

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
