Apologies for what may be a banal question, but I'm having trouble with the following:

I'm writing code that involves tracking paths and filenames for 1-100 files, which I'm doing with a 2 X N (N = number of files) cell array, where the first row contains the path(s) and the second row contains the filename(s). As entries in the same column represent a single file, I need a way to concatenate every pair of entries (:,N) to assemble full paths in another cell array. Any suggestions on how best to do this (without loops, which I'm trying to avoid, unless I shouldn't be)?

Thanks!

try this code, I can not test it, now do not have access to MATLAB

data - your cell array (size 2xN)

out = arrayfun(@(i1)fullfile(data{:,i1}),(1:size(data,2))','un',0);

For a data cell containing {'File_name', 'File_extention'} which is Nx2, then you can create a single-column cell {'File_name.File_extention'} at Nx1 with

= arrayfun(@(row)[(data{row,:})],(1:size(data,1))','UniformOutput', false);
