I'm not really sure what you're trying to do with the calculations, but this line:
F(2*n:1+2*n) =+ Force(0);
is going to result in an error, since zero is not a positive integer. Matlab uses 1-based indexing convention, so there is no zeroth index in an array. I'm assuming you meant
F(2*n:1+2*n) =+ Force(1);
since that's the only nonzero element of the array
