MATLAB: Comining the values and merging

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
