which simulink block to use in the model?

My requirements has some inputs, When i run the simulink model i want the inputs should go to m-file than use those inputs to create some data in the file which will be sent back to simulink. is there any possibilities to do like this? should i use TO FILE and FROM FILE blocks to send and retrieve data from file?

why not replace the m file with s-functions or other user-defined funcitons?
