MATLAB: Extending columns and rows of matrix

extended matrix

Hi I have a matrix like
a=[11    12   113    14
   21    22    23    24
   31    32    33    34
   41    42    43    44]
and I want to extend it to
 b=[11    12    13    14  0  0
    21    22    23    24  0  0
    31    32    33    34  0  0
    41    42    43    44  0  0
    0      0     0     0  0  0
    0      0     0     0  0  0]
how can I do that with a one line command? thank you

Or:
a(6,6) = 0;
This fills the rest with zeros automatically.
