I have used the following code to create a wsn structure with 4*4 cell grids and have deployed randomly 100 nodes in it.Now i have to give energy to all the nodes nearly 0.5 joules. How to do it? Please help

I have used the following code to create a wsn structure with 4*4 cell grids and have deployed randomly 100 nodes in it.Now i have to give energy to all the nodes nearly 0.5 joules. How to do it? Please help.

NrGrid = 4;                                 % Number Of Grids
x = linspace(0, 100, NrGrid+1);
[X,Y] = meshgrid(x);
figure(1)
plot(X,Y,'k')
hold on
plot(Y,X,'k')
hold off
set(gca, 'Box','off', 'XTick',[], 'YTick',[])
axis square
NrGrid = 4;
coords = rand(100,2) * maNrGrid + 1;
scatter(coords(:,1),coords(:,2));
set(gca, 'XTick', 1:maNrGrid+1, 'YTick', 1:maNrGrid+1)
grid on

[Walter Roberson]

energy(1:100) = sqrt(7) /2E7;

In units of kilowatt-hours, that is just under half a joule.
