The problem is that you are testing for equality of floating point values:
etc, etc, etc.
You should change your algorithm to compare the difference against a tolerance:
tol = 1e-4;
val = -2.0944;
abs(theta(:,1)-val)<tol
hii, can anyone please tell me the problem in the code ?why find doesn't give me the index of the number in theta array thanks

M=3;%sites number
N=2;%particles number
U=-1;
num_of_states= nchoosek(M+N-1,N);
fock_mat=generate_fock_states(initial_vector,M,num_of_states);
theta=centerofmass(N,M,num_of_states,fock_mat)
find(theta(:,1)==-2.0944)
any(theta(:,1)==-2.0944)
- | the result I got after running|*
theta =
0
1.0472
2.0944
-1.0472
3.1416
-2.0944
ans = Empty matrix: 0-by-1
ans = 0
