lngamma, complex argument

I'm working with the trial version of Matlab and I can't use the function 'lngamma'. Any recommendations? Than you in advanced!

You probably should try to use the function gammaln instead.

Is it applicable to complex arguments, too ?

Thank you for the answer. The problem is that gammaln is valid only for real arguments. Isn't it?

Use

and apply "log" to the result.
