you have to write following equation:
Z=A^2+B^2-2ab
in MATLAB:
syms a b c z
z=(a^2+b^2-2*a*b)

s = @(x) (1-0.4*(cos(x/100))).*(0<=x & x<=511);
x = linspace(0, 500);
R = s(x);
figure(1)
plot(x,R)
axis([xlim 0 1.5])
% intensity function
f=1/20;
x = linspace(0, 500);
I=@(x) (R(x).*sin(2*pi*f*x));
plot(x,I)
axis([xlim 0 1.5])
