How to extract complex cell data into a new variable?

I have a variable with 2000 columns. In each of the 2000 columns, there is a 1x13 cell. Within each 1x13 cell, there is a varying size double (Nx1), where N is any number. I would like to have the very 1st number within the (Nx1) double, in each of the 1x13 cells, for all 2000 columns. I would like this to result in a new cell variable with 13 columns of double 2000x1 data sets. i.e. (2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double, 2000x1 double,).
Because this is kind of confusing, I attached my code so you can open the variable yourself. To run it, it needs nodes.txt and pipes.txt. The variables name after you run the code, is "H"

Using a double loop to accomplish this is still reasonably fast:
%generate a random H
s1=2000;s2=13;
H=cell(s1,1);
for n=1:s1
H{n}=cell(1,s2);
for m=1:s2
H{n}{m}=rand(randi(100),1);
end
end
clc
tic
output=zeros(size(H,1),size(H{1},2));
for n=1:size(output,1)
for m=1:size(output,2)
output(n,m)=H{n}{m}(1);
end
end
O=mat2cell(output,n,ones(m,1));
