substitute selected array element values with those from other array

I have 2 arrays:

LNOx_vert_ocean = bsxfun(@times, apply_250_km2, lnox_mass_frac_ocean);

LNOx_vert_land = bsxfun(@times,apply_250_km2, lnox_mass_frac_land);

Both will have the size 332 x 165 x 27 x 3.

I want to substitute SOME (not all) elements in LNOx_vert_ocean with some elements in LNOx_vert_land.

The substitution will be based off of a 3rd array LU (land use). This array is 332 x 165. If the value of the elements in LU is not equal 16 then that is land. Those are the values to be substituted into LNOx_vert_ocean.

Amongst several things I have tried the following which did not work:
LNOx_vert = LNOx_vert_ocean(LNOx_vert_land(LU ~= 16));

I got the following error: ??? Subscript indices must either be real positive integers or logicals.

What am I doing wrong? I am limited to version 2009a

Thanks
Jonathan
