skip a load error

Hi,

I want to load some mat files in my folder according to a certain criteria. Sometimes this file doesn't exist. How can I continue to load the next file with causing the program to stop because of the error? example:

UID=unique(ID);

for i=1:size(UID,1) filename=['Data' num2str(UID(i,1))]; load (filename,'DataFinal')

%%% here I want to manipulate the data end

if load returns an error that such a file doesn't exist , how can I continue the loop without any interruption. Regards

You can use a try (catch) block. For example

x = 5;
try
  load('asdasdasd.mat')   %I can't load this file
catch
  disp('Did not load that last file, but it''s ok.'); 
end
x = x+1;
disp(x)

You can use exist to check if the file exists, but perhaps another approach would be to use cellstr(ls('Data*')) to get a list of the files first, then loop over those.
