MATLAB: Divide a row vector with a column vector with different dimensions

divisionmatricesmatrix arraysolvevectors

I have a problem with dividing a row vector with a column vector both different functions Quickly here is the problem from begining
the equation I want to solve for is EPD = ((H * Lambda) / (Q * GSD)) H = [500:100:1000] Q = [0.2:0.1:2] Lambda and GSD are Constants
What I have done is I created a new vector called HandLambda (Multiplied the constant Lambda with vector H) and Another vector called QandGSD (Mulitplied the constant GSD with the vector Q) then I trasnposed the new vector QandGSD and called it QandGSDreverse (Its now a column vector)
My problem now I'm trying to divide those two new vectors (different dimentions so EPD = ((H * Lambda) / (Q * GSD)) = HandLambda ./ QandGSDreverse
The division is NOT working I thought a row vector can easily be divided with a column vector even with different dimentions
Any thoughts and Ideas?? Also I'm open to change the way this can be solved!

Better if you use same sized vectors. And use './' instead of '/' to do element wise division.
 %number of points
  n=100;
  %euqally subdivide your variable intervals
  H = linspace(500,1000,n);
  Q = linspace(0.2,2,n);
  %constants
  Lambda=1;
  GSD = 2;
  %equaiton
  EPD = (H * Lambda) ./ (Q * GSD) ;
