I need to assign element in 3 D matrix that have size (x,y,z)

Index in position 3 exceeds array bounds (must not exceed 1).

for example

nz =3
nx=2
ny=3
Tz_D = zeros(nx,ny,nz); 
mobility_X = Kx./(B_O.*mu); % (nx,ny,nz)
mobility_Y = Ky./(B_O.*mu); % (nx,ny,nz)
mobility_Z = Kz./(B_O.*mu); % (nx,ny,nz)
for i = 1:nx
    for   j=1:ny
        for    k=1:nz
            if k < nz
                Tfz_U(i,j,k) =  2* mobility_Z(:,:,k+1)* mobility_Z(:,:,k)/( mobility_Z(:,:,k+1)+ mobility_Z(k,:,:)); %Tf_k- %Tf_k-
                Tz_U(i,j,k) = 0.00633*Tgz*Tfz_U(i,j,k);
                % T_j-

First of all, you need to close the loops with "end" in your code, i.e.:

nz =3;
nx=2;
ny=3;
Tz_D = zeros(nx,ny,nz); 
 mobility_X = Kx./(B_O.*mu); % (nx,ny,nz)
 mobility_Y = Ky./(B_O.*mu); % (nx,ny,nz)
 mobility_Z = Kz./(B_O.*mu); % (nx,ny,nz)
 for i = 1:nx
    for   j=1:ny
     for    k=1:nz
    if k < nz
     Tfz_U(i,j,k) =  2* mobility_Z(:,:,k+1)* mobility_Z(:,:,k)/( mobility_Z(:,:,k+1)+ mobility_Z(k,:,:)); %Tf_k- %Tf_k-
     Tz_U(i,j,k) = 0.00633*Tgz*Tfz_U(i,j,k);
    end
   end
 end
end
