I opened a .dat file for reading on Matlab. It is shown as 2 tables on Matlab , one is one-dimension with the names of the variables and the other has all the values of the variable. I changed some (10) values on Matlab and now I want to save it as a new .dat file , or just save the changes to the old. Can you help me?? thanks

There is no universal ".dat" format. Usually, it means that the file stores text. So, depending on the complexity of structure used to store said data, you could use some high-level io routines ( dlmwrite(), save '-ascii' ) or you might be forced to go low-level ( fprintf() ).
