I am trying to write a MATLAB script which calculates the gravity anomaly of a dipping prism, using the equations of Hjelt, published in Geoexploration in 1974, issue 1 volume 12.
Δg=G.Δρ.T0

and

at the end of the page there are two notes, the second one says:
"Note 2: The sign of each [itex]\phi[/itex] is positive, whenever there is an even number of 2s in the indices
of u, v and w. (u1, - v1 - w1, u1 - v2 - w2, etc.)"
I just can't get my head around what exactly this means and how to apply it.I have expanded the equations for each [itex]\phi[/itex], using the limits for u, v and w, but they are very long, so will post them only if needed.
