How to generate data?

Dear experts,
I have this code as below:
V = 10660:1:11700;
deltavB = 50:1:70;
VB = 1:1:81
a=V-VB(1); %% VB(2)....VB(81)
b=deltavB/2;
for i =1:length(b)
for j =1:length(a)
c(i,j) = (a(j)./b(i)).^2;
end
end
g = 1./(1+c);
As you can see the size of g is [21 1041] for VB(1)
I need to reapeat this for each value of VB which is 81 points, I suppose to have g [21 1041] for each value of VB
How can I do so and save it as whole data togother?
Thanks in advanced.

Try this:
V = 10660:1:11700;
deltavB = 50:1:70;
VB = 1:1:81;
all_g = zeros(length(deltavB), length(V), length(VB));
for k = 1 : length(VB)
thisVB = VB(k);
a = V - thisVB; %% VB(2)....VB(81)
b = deltavB / 2;
for i = 1 : length(b)
for j = 1 : length(a)
c(i,j) = (a(j)./b(i)).^2;
end
end
g = 1./(1+c);
% Insert this g into the k'th slice of the 3-D array all_g.
all_g(:, :, k) = g;
end
fprintf('Done!\n')

V = 10660:1:11700;
deltavB = 50:1:70;
VB = 1:1:81
numV = length(V);
numdeltavB = length(deltavB);
numVB = length(VB);
g = zeros(numdeltavB, numV, numVB);
b=deltavB/2;
for VBidx = 1 : numVB
a = V - VB(VBidx);
for i = 1:numdeltavB
c(j,:) = (a./b(i)).^2;
end
g(:,:,VBidx) = 1./(1+c);
end
The for i loop could also be eliminated by using automatic expansion. Something like
c = (a./(b.')).^2;
but you should recheck the sizes.
