I have a 3x1 Matrix containing 3 values for my velocity and I'm trying to divide these 3 values by 5 different values for thrust. To create 1 matrix that is 3x5 with each row equaling my velocity1/thrust1, velocity1/thrust2. The next row would equal velocity2/thrust1, velocity2/thrust2. etc. Ultimately I 'm trying to plot the results in each row on the same plot. If there is a better way of doing this please let me know. I have attached a picture to help explain. Thank you in advance
Edit: for the graph I'm plotting the row on the y axis and the thrust on the x axis

Implicit expansion.
velocity = (1:3).'; % column vector
thrust = 10:14; % row vector
A = velocity./thrust % Dividing results in a matrix
A = 3×5

If you prefer seeing them in rational form:
format rat
A
A =
