How can I continue with a loop when an error occurs in MATLAB?

Question

I\'m converting some .dat files into .mat files using a function. I\'m calling this function inside a loop to convert a number of files. There are some cases where my .dat file

Answer 1

You can do this using a TRY/CATCH statement along with CONTINUE. Place the following inside your loop:

try              %# Attempt to perform some computation
  %# The operation you are trying to perform goes here
catch exception  %# Catch the exception
  continue       %# Pass control to the next loop iteration
end

EDIT:

Amro suggests a good idea in his comment below. You may want to issue a warning showing that the error occurred and for which file, or perhaps you may even want to save a list of the files that failed to convert properly. To do the latter, you can first initialize an empty cell array before you start your loop:

failedFiles = {};  %# To store a list of the files that failed to convert

Then, after you catch the exception but before you issue the continue command, add the name/path of the current file being converted to the list:

...
catch exception
  failedFiles = [failedFiles; {'currentFile.dat'}];
  continue
end

When your loop is done, you can then look at failedFiles to easily see what didn't convert properly.
