i want to create a matrix which includes all numbers from 1 to n. n is given by user so i don't know n. In other words a matrix which i want to create must include n! numbers. n, n-1, n-2... n-(-n-1).

Did you look up factorial in the help?
>> n = input('Enter n : ')
Enter n : 8
n =
8
>> output = factorial(n : -1 : 1)
output =
40320 5040 720 120 24 6 2 1

I don't see how [8 7 6 5 4 3 2 1] has anything at all to do with factorial. If you want that you can simply do
output = n : -1 : 1;
but that's just super basic MATLAB stuff.
