how can I divide the vector into parts

I have a vector (1x65536). I want to divide this vector at regular intervals. but I failed. Can you help me?

for example

i = [153,142,44,22,55, ... ,52] (1x65536)

i1 = [153,142,44,55, ... , 40] (1x20)

i2 = [144,122,144,655, ... , 40] (1x20)

.

.

.

ixx = [44,55,77,22, ... , 52] (1x16)

data_cell=mat2cell(data,1,[20*ones(1,3276),16])

Result, save the all sub array data in cell array having cell elements 3227, where all cell element size is 1x20, except last one, which is 1x16

>> whos data_cell
  Name           Size               Bytes  Class    Attributes
  data_cell      1x3277                ??  cell
