I have established a connection between the matlab and the ODBC server of mine. This is the data type which i am trying to fetch
Columns 1 through 8
  'NIFTY' 'FUTIDX'  'FF'  
Columns 9 through 12
'14:43:37'   
As every one knows that the data is stored in a cell array format, the time stamp that is the column 9, is getting stored as a character array.
This is causing me problem i want to operate on the time stamps i.e. i want to check the data after every 5th minute. Since the data is getting stored as character this is not possible.
Can anyone help me here?
