ajeet - is there anything more to this equation? Is r0 a matrix or a function? If a matrix, then presumably x and y are integers and so your equation could be written as
x = 1;
y = 2;
r0 = rand(4,4); % sample data to illustrate problem
r = zeros(4,4);
R = 1;
r(x,y) = 2 * round((R - 1) / 2) + ((-1)^(R + 1)) * r0(x,y);
But how is R used. You mention that R is equal to 1,2,3,4. Does this mean that you have 4 matrices (of r) where you use different values of R. Or is have you omitted a summation? Please clarify.
