How to judge "load" function

Hi guys:

Is there a way to judge whether a '.txt' file could be loaded by "load" function?

Some of my files are matrix which could be loaded by "load" but some are not.

Is there a way to separate them?

Thanks a lot

You could perform the load in a try/catch block and react accordingly:

 try
     load(filename);
 catch e
    % Something went wrong -- not a valid file to load?
 end

Thanks a lot.

Forgot the matlab has try.
