How can i sort a matrix with loops?

I need to sort each row of a matrix (without sort function) in ascending order using loops and im confused about how i would go about switching values within the row to order them.

x = [1 2 5 4]

For example, t switch the 5 and the 4

x([3 4]) = x([4 3]) %switch linear indices.
