Het guys, i attached a code here. The problem is that the very first 'R' matrix i have to get is a Identity Matrix. Unfortunately, i don't know what went wrong there is some mistake. Could anyone shed some light, what i did wrong?. Thanking you in advance.

I get the identity matrix with your code:
>> phi = 0;
>> psi = 0;
>> theta = 0;
>> R=[cosd(phi).*cosd(psi)-sind(phi).*cosd(theta).*sind(psi) sind(phi).*cosd(psi)+cosd(phi).*cosd(theta).*sind(psi) sind(theta).*sind(psi)
-cosd(phi).*sind(psi)-sind(phi).*cosd(theta).*cosd(psi) -sind(phi).*sind(psi)+cosd(phi).*cosd(theta).*cosd(psi) sind(theta).*cosd(psi)
sind(phi).*sind(theta) -cosd(phi).*sind(theta) cosd(theta)]
R =
1 0 0
0 1 0
0 0 1
