The gamma function.
y = gamma(x)
scalar, vector, matrix, or hypermatrix of real numbers.
![]() | gamma can be overloaded for complex numbers or
of lists, tlists or mlists. |
real vector or matrix with same size than x.
gamma(x)
evaluates the gamma function at all the
elements of x
. The gamma function is defined by
:
and generalizes the factorial function for real numbers
(gamma(u+1) = u*gamma(u)
).
