Classes

class  gmx::ArrayRef< typename >
 STL-like interface to a C array of T (or part of a std container of T). More...
 
class  gmx::ArrayRefWithPadding< typename >
 Interface to a C array of T (or part of a std container of T), that includes padding that is suitable for the kinds of SIMD operations GROMACS uses. More...

Functions

SettleParameters gmx::settleParameters (real mO, real mH, real dOH, real invmO, real invmH, real dHH)
