You still have not done what was asked. What should the output look like for that input?

To visualize your data:
plot3(In(:,1), In(:,2), In(:,3), '-mo','LineWidth',2,'MarkerFaceColor', [.2 .2 .2]); grid on;

then what do you mean by box counting? How large should your bins be?

Possibly something like,

[ linspace(C1min, C1max, NumEnt) .' ;
linspace(C2min, C2max, NumEnt) .' ;
linspace(C3min, C3max, NumEnt) .' ]


But that would only be a 2D matrix not 3D.
