Reading value from text file for every 10ms?

Hi I need to read a value from a text file for every 10millisec which is input to my model (i give this value to a constant block which is input to the model). When i first start the simulation i should read the first value, after 10ms constant block should be able to read the second value and so on. Can anyone guide me through this problem. The reason i need to wait 10millisec is that the file is updated for every 10ms from external source.

Simulink?

Also is the file being updated and that is why you need to wait? Or could the entire file be read in at the same time as long as the values were delivered one at a time ?

I'm pretty sure you can't update a constant block when the model is running.

hi.

Use the following command

for i = 1 : xx  
  x = dlmread(filename, delimiter);
  pause(0.001);
end
