How to make residuals and X & Y data dimension equal?

I am doing a polynomial curve fitting and I have x & y dimension are 1x20 but the residuals plot dimension i was getting is of 20x1....So i am not able to plot the residual plot in command line after saving ow to my fit. Plz tell how to make dim equal so that i can plot residuals?

Would just taking the transpose work? When a vec is nx1, then vec' is the equivalent 1xn vector.

Can u tell how it can be done in cftool? As residuals are in output block of fittedmodel of workspace...
