MATLAB: Constructing file identifier from string

You can initialize file identifiers as an array, and use them in loop.

fullfileKBDR = strcat('/Users/jkoval/Documents/MATLAB/archived_fod_forecasts/output/KBDR_','.csv')
fid(1) = fopen(fullfileKBDR, 'w')
fprintf(fileID1,formatSpec)
fullfileKMHT = strcat('/Users/jkoval/Documents/MATLAB/archived_fod_forecasts/output/KMHT_','.csv')
fid(2) = fopen(fullfileKMHT, 'w');
fprintf(fileID2,formatSpec)
fullfileKASH = strcat('/Users/jkoval/Documents/MATLAB/archived_fod_forecasts/output/KASH_','.csv')
fid(3) = fopen(fullfileKASH, 'w');
fprintf(fileID3,formatSpec)
fullfileKPWM = strcat('/Users/jkoval/Documents/MATLAB/archived_fod_forecasts/output/KPWM_','.csv')
fid(4) = fopen(fullfileKPWM, 'w');
fprintf(fileID4,formatSpec)
for n = 1:4
    %Do stuff
    nasstr = string(n)
    fid(n)   % this gives file identifier 
end

MATLAB: Reordering string arrays if string is >9

sort_nat is powerful, and has helped me several times.

An alternative for simple number/not-number values is straightforward

find the locations of the numbers
sort those
append the not-numbers

 z = cellfun(@(X) logical(~isempty(str2num(X))),b);  % z shows locations of number strings
 n = cellfun(@str2num, b(z));  % into numerical
 [~, ix] = sort( n );  % ix tells what order to pull from b
 r = b(ix);  % fill the result using sorted numbers
 r{end+1} = b{~z};  % append the not-numbers
