Not same fprintf MATLAB and Linux Console

12 views (last 30 days)
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',;
errorMessage2 = sprintf('Error in line %d\n',ME.stack(1).line);
errorMessage3 = sprintf('Error %s()\n',ME.message);
fprintf(2,'%s\n', errorMessage1);
fprintf(2,'%s\n', errorMessage2);
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,

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

@Javier: Sorry, my mistake.
./matlab -r "cd('~/folder1'); getOutput" -nosplash -nodesktop
The parameter of the -r command must contain a valid Matlab command, not the path of a m-function. You can find more details in the documentation:
