I want to divide an array up into sections and add each section to its own column in a table.

29 views (last 30 days)
I have an array that is 85x48 and I want to break it up into 6 sections of 85 x 8 and make each of those arrays into one column of a table.
ie. Columns 1-8 of the array will be column 1 of the table, columns 9-16 will be column 2 etc.
The size of my array (85x48) may change and thus the number of sections and their size might also change, so I need to set it up so there is not a set number of columns already in the table and I am just manually assigning the data each time.
I have tried using a for loop that determines the starting and ending column for each section and adds that to a table, but I do not know how to specify which column in the table I want it to be written to, so it only ever writes to the first column and writes over all of the previous data.
Any help would be greatly appreciated
rows = 8; %these numbers will change so the table needs to work for any iteration
columns = 6;
wells = 48;
example = rand(85,48);
n_end = 0:rows:wells; %creating an array to specify where the table should be cut
n_start = n_end +1;
n_end(1) =[];
n_start(end)=[];
n_times = [n_start;n_end];
for i = 1:columns
x = example(:,n_times(1,i):n_times(2,i));
Organized_table = table(x);
end

example = rand(85,48);
sections = 6;
T = cell2table(mat2cell(example, ones(1,size(example,1)), sections*ones(1,size(example,2)/sections)))
T = 85x8 table
