Trying to wrangle serial data from an Arduino

Processing Electronics (Arduino, etc.)

I guess if that is your definition of help, I don’t really want help; I want advice on how I take serial data that looks like this:

233 230 254 296 357 436 486 513 519 528
235 253 290 346 410 477 516 539 550 558
229 252 295 351 424 486 513 533 537 544
230 254 296 357 436 486 513 519 528 535
End

and put it into an array in Processing that looks like this:

int[][] LiDARdata = { {179, 169, 172, 183, 201, 220, 251, 297, 359, 432}, 
                      {174, 177, 192, 207, 224, 248, 289, 343, 408, 484}, 
                      {167, 175, 187, 203, 224, 256, 298, 355, 431, 490}, 
                      {169, 172, 183, 201, 220, 251, 297, 359, 432, 484} };

I don’t really want someone to write my code for me, just give me some advice, clues, tips or whatever it is that I’m not picking up on from reading the official documentation for the past couple of days.
