I am using intel MKL for linux version=10.2.2.025. I can not find gamma() in the VML special function lists. Any idea? Thanks.

You can't because there is not (I believe). You can get source code here.

Thanks.

yjyincj,there are no such functionality into the current version.
I would recommend you submit the issue against MKL to Premier support( https://premier.intel.com/ )

You will findthe"true" gamma functionin the Intel Compiler provided math library libimf.a(described here -http://software.intel.com/sites/products/documentation/hpc/compilerpro/en-us/cpp/lin/main_cls_lin.pdf).Its prototype is double tgamma(double). Note that both the lgamma() and gamma() functions return not gamma but the log gamma for historical reasons.

There is an article that maybe can help you.

Calling the lgamma function from the Intel Fortran Compiler. You can find it in the search bar.
