Thanks Jed. After configuring using this, how can I turn on the debugging option when I compile the code?

A segmentation violation error jumps out when I set value for the very first element in the matrix. There is no problem for me to run the program when turning on the debugging option. I just want to tune this for better performance. Or is it better to turn on the debugging option? Could anybody help me with this? Thanks!
