%Program for flow over a bicycle clear all close all clc %Drag Coeeficients for various shapes c_d=[0.47,0.42,0.50,1.05,0.80,0.82,1.15,0.04,0.09]; %Area in m^2 a=0.1; %Density kg/m^3 rho=1.2; %velocity m/s v=(1:9); Drag_Force=0.5*rho*a*v.*v.*c_d; plot(v,Drag_Force,c_d,Drag_Force) xlabel("Velocity and Coefficient of Drag") ylabel("Drag Force") 

I got an error in this line "c_d=[0.47,0.42,0.50,1.05,0.80,0.82;1.15,0.04,0.09];". I searched online for any solution, But i could'nt find any solution. After that I checked out my code for errors then I rectified the error.

As shown in the image below i got an error indicating that error using *. I found out that error was due to the use of an array with different size. So I increased the velocity range from 1:5 to 1:9. Then i got an error saying that error in line 15. So I watched the tutorial again and found out that for the product of an array a dot need to be used to indicate dot product.
