MATLAB: Specify directory and automatic save files in loop

save in loop

Hello everybody: I have a matrix have composed of several columns sometimes 24 other times 6 etc. I want to choose a folder and then automatic save colums as wav files such as: 1.wav, 2.wav ….24.wav, but this code failed to work ?? Does anybody know how to do it ??
folder = uigetdir(); % Or wherever you want.
for i = 1 : n  
    % Create a filename.
    baseFileName = sprintf('Cell%d.wav', i);
    filename = fullfile(folder, baseFileName);
    % Write the wav files.
    wavwrite(mat(:,i),Fs,16,filename);
    end

Dear All I found the solution;
A loop for automatic saving files..
it write every column in a matrix called mat, column by column You just choose the name of the exported files like "file' and chhose the folder, then the loop will save automatically all files like (file1.wav, file2.wav etc). You can use it for any other file types such as xls or txt, you will only have to change the write command like 'xlswrite" "dlmwrite" etc.
 %Write ALL wave files
 Fs=input('Enter The the sampling frequency (No. of samples/second) ='); % this will be used in the 
 frequency Axis
 name = input('Enter File name? :','s');
 Origin_Name= name ;
 [file,path] = uiputfile('*.wav');
 FileName = fullfile(path,file);
 for i=1:n
 FileName=[Origin_Name,num2str(i)];
 wavwrite(mat(:,i),Fs,16,FileName);
 end
