GDB question: Pretty-Printing a 2D Array?

Question

I have a 2d array matrix[10][10] that I\'d like to inspect at debug time.

I understand that I can do this in GDB using

p *matrix@10

Answer 1

Can you do this?:

p *((double (*)[3][3])pointerToMatrix3x3)

   (double [3][3]) $6 = {
  [0] = ([0] = 1821.8790830216928, [1] = 0, [2] = 1622.4513098457062)
  [1] = ([0] = 0, [1] = 1172.3930433142486, [2] = 1314.4812787191868)
  [2] = ([0] = 0, [1] = 0, [2] = 1)

p *((double (*)[4])pointerToVector4)

  (double [3]) $7 = ([0] = 1821.8790830216928, [1] = 0, [2] = 1622.4513098457062)

It works in lldb - Haven't tried it in gdb. It seems a lot easier.
