GAMMAFUNCTION (z)
- is any positive real number.
is any positive real number.Description
- This function gives the value of the Gamma function.
- The Gamma function is defined to be an extension of the factorial to complex and real number arguments.
- That is, if n is a positive integer:
- Gamma function is defined for all complex numbers except the non-positive integers.
- For complex numbers with a positive real part, it is defined via a convergent improper integral:
