Comining the values and merging

A=
   ''      'c0'      'c1'      'c2'    'c3'     'c4'    'c5'     'c6'

'yar12'  'hi'     'hello'   'hi'   'hello'   'hi'        'hi'    'hi'

'yar13'   hello'  'hi'      'hi'   'hello'   'hi'         'hi'    'hi'

'yar14'  'hi'     'hi'      'hi'   'hello'    'hello'    'hello'  'hi' 

'yar15'  'hello'  'hi'      'hi'   'hi'      'hi'        'hi'   'hello'   

'yar16'  'hello'  'hi'      'hi'   'hello'   'hello'      'hello'

'yar17'  'hi'     'hi'      'hi'    'hi'      'hi'       'hi'    hello' 

I need to combine intervals

c0c1c2c3

c1c2c3c4

c2c3c4c5

c3c4c5c6

so for example for yar12

   'c0c1c2c3'        'c1c2c3c4'      'c2c3c4c5'    'c3c4c5c6'

  
'yar12'  'hihellohihello' 'hellohihellohi' 'hihellohihi' 'hellohihihi'

like this i need for all values from yar13 to yar130(for sample i have posted till yar17)

please help

 A=   {''      'c0'      'c1'      'c2'    'c3'     'c4'    'c5'     'c6'
'yar12'  'hi'     'hello'   'hi'   'hello'   'hi'        'hi'    'hi'
'yar13'   'hello'  'hi'      'hi'   'hello'   'hi'         'hi'    'hi'
'yar14'  'hi'     'hi'      'hi'   'hello'    'hello'    'hello'  'hi'
'yar15'  'hello'  'hi'      'hi'   'hi'      'hi'        'hi'   'hello'
'yar16'  'hello'  'hi'      'hi'   'hello'   'hello'      'hello' 'hello'
'yar17'  'hi'     'hi'      'hi'    'hi'      'hi'       'hi'    'hello' };

A2 = num2cell(A,1);
idx = hankel(2:5,5:8);
out = [A2(:,1),arrayfun(@(i1)strcat(A2{idx(i1,:)}),1:size(idx,1),'un',0)];
out = [out{:}];

[Oleg Komarov]

B = num2cell(A,1);
B = [B{:,1} strcat(B{2:5}) strcat(B{3:6}) strcat(B{4:7}) strcat(B{5:8})];
