MATLAB: Command to calculate the coordinates of points

MATLABmatrix algebra

Hi, I calculating the coordinates of the points in this way:
P1 = [X (1), (- A (1) - Y (1))];
P2 = [X (2), (- A (2) - Y (2))];
P3 = [X (3), (- A (3) - Y (3))];
P4 = [X (4), (- A (4) - Y (4))];
P5 = [X (5), (- A (5) - Y (5))];
P6 = [X (6), (- A (6) - Y (6))];
P7 = [X (7), (- A (7) - Y (7))];
where X, Y and A are column-vectors
How can I calculate the coordinates of the points with a single command? thanks so much
Max

Best Answer

 P = [X (-A-Y)];
 P1 = P(1,:)
 P2 = P(2,:)
