All Gurus, Although Microsoft's Excel is applicable to some of SI's calculation, but It's not a pratical method for recursive calculations, because it's running time is very long. Ofcourse, I believe you can writes own codes for SI analysis. As we known, lot of engineers often write Mathlab codes to do thier analysis. But Do you consider whether the running speed is comaparable to those commercial tools which dedicated to SI? Writing codes and writing speedy codes are different things. Ultraeditor will replace 10,000,000 instances of a character in seconds. Notepad also can do same things but in hours, Wordpad in less hours, Winword in ten minutes.
