Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 5-by-1.

Looks like Cd and rho are vectors. So the result of those calculations on the right hand side will be vectors. But you are trying to stuff them into a scalar element. You need to rethink what you are doing.

I think it will be easier to help find the problem, if you provide either the excel-sheet, the workspace variables, or if you type in Cd and rho manually, since these are not available when you just give the script.
