MATLAB: Split array into sub arrays

array

Hi,
I am trying to split some data in x,y,z:
   x = [351;333;337;341;346;350;354;359;363;368;372;377];
   y = [145;180;182;184;186;188;190;192;194;195;197;198];
   z = [31;31;30;28;28;26;24;23;21;20;19;18];
based on the values of another array named data:
   data = [0,0,0,2,0,0,1,0,0,0,0,0];
So that when data = 2, the following values of x, y and z are calculated until data = 1. So in this case the data would be split into the following:
When data hits equal to 2:
   x = [351;333;337;341];
   y = [145;180;182;184];
   z = [31;31;30;28];
And then up until data = 1:
   x = [346;350;354];
   y = [186;188;190];
   z = [28;26;24];
and finally the after 1..
   x = [359;363;368;372;377];
   y = [192;194;195;197;198];
   z = [23;21;20;19;18];
However I am really struggling getting this to work, it either extrapolates x, y and z when data is equal to 2 or brings up errors. Any help would be appreciated.
Cheers

Or use mat2cell,
 res = mat2cell([x y z].',3,diff([0 find(data) numel(data)]))
you get the result in a cell array, each cell containing the data split you want
>> res{1}
     351   333   337   341
     145   180   182   184
      31    31    30    28
>> res{2}
     346   350   354
     186   188   190
      28    26    24
>> res{3}
     359   363   368   372   377
     192   194   195   197   198
      23    21    20    19    18
