Passing a vector through a built in function?

Hello,

I am passing two vectors through and equation, but am getting a scalar output. The equation is as follows:

V=sqrt((2*W*cosd(theta))/(CL*p6000));

W and p6000 are constants.

theta and CL are vectors, of the same length.

When I run the code as is seen above, I get a scalar output instead of a vector. When I try to use the dot operator, i get an error saying matrix dimensions do not agree.

How do you fix this?

Thanks

Do element-wise multiplication and division:

V=sqrt((2*W.*cosd(theta))./(CL*p6000));
           ↑             ↑
