MATLAB: Not same fprintf MATLAB and Linux Console

catchconsoleerrorfprintflinuxtry

Hello everybody,
I am trying to catch an error and I have made the following code in Matlab:
catch ME
            % Some error occurred if you get here.
        errorMessage1 = sprintf('Error in function %s()\n',ME.stack.name);
        errorMessage2 = sprintf('Error in line %d\n',ME.stack(1).line);
        errorMessage3 = sprintf('Error %s()\n',ME.message);
        fprintf(2,'-----------------------------\n');
        fprintf(2,'%s\n', errorMessage1);
        fprintf(2,'-----------------------------\n');
        fprintf(2,'%s\n', errorMessage2);
        fprintf(2,'-----------------------------\n');
        fprintf(2,'%s\n', errorMessage3);
The output of Matlab is the following one:
Error in hello()
Error in line 386
Error Index exceeds matrix dimensions.()
But, when I execute matlab from de Linux console:
./matlab < hello.m
I just get this output:
Index exceeds matrix dimensions
I cannot see the line or the .m I am running.
What kind of problem is this?
Thanks in advance,
Javi

If you write the message to stderr by
fprintf(2, '%s\n', errorMessage1);
you have to catch this channel also. Try:
fprintf(1, '%s\n', errorMessage1);
Perhaps this works instead, but I cannot try it currently and hopefully someone corrects me:
matlab -r hello.m 2>&1
