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.
