tic and toc to calculated the simulation time...but the this not the same everytime...

I am using a tic and toc command to calculate the simulation time of my matlab program...However, i found out that the time is different for every time...how to solve this or is there any other method that can be use to calculate the simulation time for matlab program?

The running time of your program is going to be slightly different every time because the OS does slightly different things while your program is running (it might check for viruses, download updates, refresh the screen, etc.). This means TIC/TOC should return different values.

[Dennis Ting]

that mean it is impossible to get the same reading for the simulation time for each simulation?

Yes. Going off to use your web browser in the middle of a test can be a killer too. You can improve things by downloading timeit from the file exchange though. You will ALWAYS see some variability in the computed time.
