cell array to matrix

I have a cell array with 4 elements.Each with 2*2 dimensions. I want to create an 8*2 matrix with these cell arrays. I can do it as p_all=[p{1};p{2};p{3};p{4}] but it will be in a loop and I will not the know the number of elements beforehand although all the elements will be 2*2. Any suggestions?

p{1} =

      89    62
      89   166

p{2} =

     132   167
     132   208

p{3} =

     113   208
     113   281

p{4} =

      64   281
      64   320

Assuming that the sizes are compatible you can easily use a comma-separated list:

vertcat(p{:})
