I'm not entirely sure I understand what you're asking for help with, but if I understand correctly you're not sure how to progressively index the columns of the bigArray? I don't see a loop for the different sets of singleJac that you want to put into the bigArray, where do the other six come from? (The data from columns 6-10, 11-15, etc)
The way I know how to put data in progessive sets of columns is with a quick loop. See the arbitrary example below for a visual. It's just a matter of indexing with variables.
% I want to put a series of 5x5 arrays into a larger 25x25 array
big = nan(25); % Create big array of nans, 25x25
for i = 1:size(big,1)/5; % Determine number of 5x5s will fit bigger rows
for j = 1:size(big,2)/5; % Same as above for columns
small = randi(100,5); % Create random 5x5 matrix
big(5*(i-1):5*i,5*(j-1):5*j) = small; % Insert small array into big array
end
end
