"Want the matricies for vector that is created to be seperate."
What exactly does that mean? I'm assuming "matrices" means "vector", but that's still ambiguous. You want the outputs to be separate, but how exactly?
theta = [0,45,90];
F = 450;
% one row for each theta
matrix = F.*[cosd(theta.') sind(theta.') [0; 0; 0]]
% one row for each axis
matrix = F.*[cosd(theta); sind(theta); [0 0 0]]
That gives the result as a matrix. You can index within the matrix to find the vectors you want. If you want three separate vector variables, then I have no idea why you were trying to vectorize it in the first place.
If none of this is what you want, you'll have to clarify your description of how you want the output to be arranged.
