Syntax: |
y = FACTORIAL(x)
|
The FACTORIAL
function is an element by element
function that returns the factorial of the argument. The argument can be a scalar, vector
or matrix. A scalar argument results in a scalar. A vector argument results in a vector
with the same length as the argument, and a matrix (tensor) argument results in a matrix
(tensor) with the same dimensions as the argument.
The integer portion of the argument value is used to calculate the factorial. For example,
if n = INT(x)
, then
FACTORIAL(x) = n(n-1)(n-2)...(2)(1)
.
