MATLAB: Segregate data

Question

P =

Columns 1 through 12
    14    15    16    17    18    19    20    21    22    23    24    25
Columns 13 through 24
    86    87    88    89   273   274   275   276   337   338   339   340
Columns 25 through 32
   341   342   343   344   345   346   347   348

I want segregate this data into two group.(14-89) into one group and (273-348) into another group.

Answer 1

out = reshape(P,numel(P)/2,[])'

or

out = mat2cell(P,1,numel(P)/2*[1 1])

or

t = P < 100;
out = {P(t) P(~t)}
