How to use a batch mode to import files?

Hi, I have 3 files named 1.xlsx, 2.xlsx, 3.xlsx in a folder. Now, I want to run all the three files at a time using a batch mode. I have written a for loop code but I does not work. It brings out the first result, but it is failing to process all the three files. However, it does not show any error.It just shows the results of the first file and stops.

files = dir('C:\Users\Deakin Uni\Documents\MATLAB\a\*1*');
fNames = {files.name};

%for each file
for k= 1: length(fNames)
   % extract file name
   fName = ['C:\Users\Deakin Uni\Documents\MATLAB\a\', fNames{k}];
   [XDATA, TIMESTEPS] = importfile(fName);
a1 = XDATA - mean (XDATA);
plot(TIMESTEPS, a1);
[peakvals,peaklocs] = findpeaks(a1, 'minpeakdistance',50, 'minpeakheight', 0.00001);
peaktime = TIMESTEPS(peaklocs);
createfigure4(TIMESTEPS, a1, peaktime, peakvals)
saveas(gcf, 'chaitu.fig') 
end

Thanks in advance!!

Have you checked length(fNames) ?

As in? There are 3 files in the folder with the names 1.xlsx, 2.xlsx, 3.xlsx

From this: files = dir('C:\Users\Deakin Uni\Documents\MATLAB\a\*1*');

it looks like you're only loading the first one... shouldn't it be:

    files = dir('C:\Users\Deakin Uni\Documents\MATLAB\a\*.xlsx');

GREAT!! that works. However, i want all the 3 graphs to be saved under different names. Any help?

[Chaitanya Bade]

I got that one as well. Thanks heaps!!!

[JohnGalt]

you got the separate graphs sorted?

[Chaitanya Bade]

Yes. I used the following code saveas(gcf,sprintf('chaitu%d.fig',k));
