Oh maybe that's why then. My equations are dependent upon angles. These angles range from negative to positive values. If that is why I am getting an error, how am I suppose to work around that so that I can still use fzero?

My inputs are definitely vectors.

okay I fixed that problem but now I'm getting this error:

??? Error using ==> fzero
FZERO cannot continue because user supplied function_handle ==> @(Velocity)(0.5*C_D1*p*A_o*(Velocity^2)*((1000^2)/(3600^2)))+F_grav+F_rolling+Force_Car
failed with the error below.

Error using ==> plus
Matrix dimensions must agree.

lol, I can't win for losing!?!?!?!?!
