Function Documentation

RealVect BASISREALV (  int    idir )

Returns a basis vector in the given coordinate direction. In 2-D: BASISREALV(0) == (1.,0.); BASISREALV(1) == (0.,1.). In 3-D: BASISREALV(0) == (1.,0.,0.); BASISREALV(1) == (0.,1.,0.); BASISREALV(2) == (0.,0.,1.). Note that the coordinate directions are based at zero.
