factorial - Factorial function
Syntax
factorial(N)
Description
factorial(N), for scalar N,
is the product of all the integers from 1 to N,
i.e. prod(1:n). When N is an N-dimensional
array, factorial(N) is the factorial for each element of N.
Since double precision numbers only have about 15 digits, the answer
is only accurate for n <= 21. For larger n,
the answer will have the right magnitude, and is accurate for the first 15
digits.
