difficulty in plottin 3d plot using matlab-help plz

F=50e9;
C=3e8;
Lambda=C/F;
t=[6 6 6 6 6 6 6 6 6];
TRL=[0.0030 0.0030; %represent position
0.0030 0.0060;
0.0030 0.0090;
0.0060 0.0030;
0.0060 0.0060;
0.0060 0.0090;
0.0090 0.0030;
0.0090 0.0060;
0.0090 0.0090];

TRx1=TRL(:,1);
TRx2=TRL(:,2);
figure,stem3(TRx1,TRx2,t,'^')
hold on
xlabel('distance between transmitter in mm')
ylabel('distance between transmitter in mm')
zlabel('length of transmitter ')
legend('transmitter')

N=9;
d = 1:N;
d0=1;

Pt=1; %Transmited Power


Pr=Pt*(1./(d.^2));


Pr = 10.*log(Pr);

i have to plot Pr in three dimensional, along with the above figure which is generated.. plz help
