hi

what i mean by '' cover '' is to run the for loop and use all the vector values of the variables a, b and y

(ie. a = [1 2 3 4 5 6 7 8 9 ] ....b = [ 7 6 5 4 ] . .. . y = [1 2 5 6 7 ] )

so the for loop will cover every possible combination within these variables

[A, B, Y] = ndgrid(a, b, y);

k = A + B + Y;

disp(k(:));

Another approach is to give the three vectors different orientations and
then use BSXFUN twice.

a = 1:9;
b = 7:-1:4;
c = [1 2 5 6 7];
ab = bsxfun(@plus, a, b.');
abc = bsxfun(@plus, ab, reshape(c, 1, 1, []));
