how can i use my function just ones?

hello i have a function and a problem :)

function[result] = transform_vertices(v, m)

    for i = 1 : size(v,2)
        v(:,i) = m * v(:,i); %m * ith coloumn of v 
    end
    result = v;
end

i should use this function(transform_vertices) just ONCE to rotate ,translate but how can i use just once? my code is

image1_vertices = quad;
image1_vertices = transform_vertices(transform_vertices(quad,mrotate(30)),mtranslate(-2,0));
PS: mtranslate and mrotate are also function which calculates rotation,translation

can anyone help ?

Your question is somewhat vague, but I'll hazard an answer. The operation of multiple rotation would presumably require a power, not a multiple, be taken of the single rotation matrix. You appear to be simply taking a scalar multiple in your code.

Please give a lot more details.
