No, there is no built-in tool for that .

Have you considered applying a rotation and translation ? makehgtform is convenient for creating transformation matrices

z = zeros(size(x));

[x(:), y(:), z(:), zeros(numel(x),1)] * Matrix

and take the first two columns of the output

I show z separately because this is the general form for when you have x y z coordinates, that you use them as the first three columns and the fourth needs to zeros
