WebDec 31, 2016 · I believe that some the Intel RT libraries (such as libmmd.lib) contain a gamma function callable from C. I can only see lower-case names containing 'gamma' in the symbols in, for example, libmmd.lib. I believe that that function gives ln Γ(x), rather than Γ(x). Fortran 2008 provides the gamma function, but your 11.1 compiler probably does … WebFortran 90 offers the possibility to define both types and overloaded operators. These two key features make Fortran 90 particularly suitable for writing QCD programs at a very high level where the algorithms are transparent and compact. On the other hand, by maximizing efficiency of the code in the definition of the overloaded operators ...
