How to group elements of a logical array?

Hello,

I have a logical array of size 64x256. I want the result to be a cell array of size 64x16 where each cell has 16 bit data.I have attached an image of my data for reference.

For eg: Let T be the logical array

     T= 0 0 0 0 0 0 1 0 1 1 0 0 0 0 1 0  0 0 0 0 0 0 0 1 0 1 0 1 1 1 0 0 0 0 0 0 0 0 0 1 1 1 0 0 1 1 0 0
        0 0 0 0 0 0 1 1 0 1 1 1 1 1 1 0  0 0 0 0 0 0 0 1 1 1 0 0 0 1 1 0  0 0 0 0 0 0 1 1 0 1 0 0 0 0 0 0
        0 0 0 0 0 0 1 1 1 0 1 1 1 1 1 1  0 0 0 0 0 0 0 0 1 1 0 0 1 1 0 1  0 0 0 0 0 0 0 1 1 0 1 1 1 0 1 0
        0 0 0 0 0 0 1 1 0 1 1 0 1 0 1 0  0 0 0 0 0 0 1 0 0 0 0 1 1 0 0 0  0 0 0 0 0 0 1 0 1 1 1 0 1 0 0 1
        0 0 0 0 0 0 1 0 1 1 1 0 1 0 1 1  0 0 0 0 0 0 0 0 0 1 0 0 0 0 1 1  0 0 0 0 0 0 1 0 1 0 0 0 0 1 0 1

I want an output such that the cell data are grouped into 16 bit binary data as follows

    T1='0000001011000010'  '0000000101011100'  '0000000111001100'
       '0000001101111110'  '0000000111000110'  '0000001101000000'
       '0000001110111111'  '0000000011001101'  '0000000110111010'
       '0000001101101010'  '0000001000011000'  '0000001011101001'
       '0000001011101011'  '0000000001000011'  '0000001010000101'

I tried reshape array but error message is shown.How to do it? Please help...Thanks in advance...

You could use mat2cell and sprintf like this:

T = [0,0,0,0,0,0,1,0,1,1,0,0,0,0,1,0,0,0,0,0,0,0,0,1,...
    0,1,0,1,1,1,0,0,0,0,0,0,0,0,0,1,1,1,0,0,1,1,0,0;...
    0,0,0,0,0,0,1,1,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,...
    1,1,0,0,0,1,1,0,0,0,0,0,0,0,1,1,0,1,0,0,0,0,0,0;...
    0,0,0,0,0,0,1,1,1,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,...
    1,1,0,0,1,1,0,1,0,0,0,0,0,0,0,1,1,0,1,1,1,0,1,0;...
    0,0,0,0,0,0,1,1,0,1,1,0,1,0,1,0,0,0,0,0,0,0,1,0,...
    0,0,0,1,1,0,0,0,0,0,0,0,0,0,1,0,1,1,1,0,1,0,0,1;...
    0,0,0,0,0,0,1,0,1,1,1,0,1,0,1,1,0,0,0,0,0,0,0,0,...
    0,1,0,0,0,0,1,1,0,0,0,0,0,0,1,0,1,0,0,0,0,1,0,1];
S = size(T);
X = mat2cell(T,ones(1,S(1)),16*ones(1,S(2)/16));
Y = cellfun(@(v)sprintf('%i',v), X, 'UniformOutput',false);

Which produces two useful cell arrays:

>> X
X = 
  [1x16 double]    [1x16 double]    [1x16 double]
  [1x16 double]    [1x16 double]    [1x16 double]
  [1x16 double]    [1x16 double]    [1x16 double]
  [1x16 double]    [1x16 double]    [1x16 double]
  [1x16 double]    [1x16 double]    [1x16 double]
>> Y
Y = 
  '0000001011000010'    '0000000101011100'    '0000000111001100'
  '0000001101111110'    '0000000111000110'    '0000001101000000'
  '0000001110111111'    '0000000011001101'    '0000000110111010'
  '0000001101101010'    '0000001000011000'    '0000001011101001'
  '0000001011101011'    '0000000001000011'    '0000001010000101'

This may or may not be faster than Stephen's answer. Pick whichever you prefer:

T = [0,0,0,0,0,0,1,0,1,1,0,0,0,0,1,0,0,0,0,0,0,0,0,1,...
    0,1,0,1,1,1,0,0,0,0,0,0,0,0,0,1,1,1,0,0,1,1,0,0;...
    0,0,0,0,0,0,1,1,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,...
    1,1,0,0,0,1,1,0,0,0,0,0,0,0,1,1,0,1,0,0,0,0,0,0;...
    0,0,0,0,0,0,1,1,1,0,1,1,1,1,1,1,0,0,0,0,0,0,0,0,...
    1,1,0,0,1,1,0,1,0,0,0,0,0,0,0,1,1,0,1,1,1,0,1,0;...
    0,0,0,0,0,0,1,1,0,1,1,0,1,0,1,0,0,0,0,0,0,0,1,0,...
    0,0,0,1,1,0,0,0,0,0,0,0,0,0,1,0,1,1,1,0,1,0,0,1;...
    0,0,0,0,0,0,1,0,1,1,1,0,1,0,1,1,0,0,0,0,0,0,0,0,...
    0,1,0,0,0,0,1,1,0,0,0,0,0,0,1,0,1,0,0,0,0,1,0,1];

T1 = reshape(cellstr(char(reshape(T', 16, [])+'0')'), [], size(T, 1))'

outputs:

T1 = 
  '0000001011000010'    '0000000101011100'    '0000000111001100'
  '0000001101111110'    '0000000111000110'    '0000001101000000'
  '0000001110111111'    '0000000011001101'    '0000000110111010'
  '0000001101101010'    '0000001000011000'    '0000001011101001'
  '0000001011101011'    '0000000001000011'    '0000001010000101'
