friend pvector Idag(const pvector& in1) friend pvector Jdag(const pvector& in1)Return value:
- Idag: action of complex-conjugate of discrete Fourier transform on in1. (Code is just like I() but sends ``-1'' to fournp480 instead of ``1''.)
- Jdag: action of complex-conjugate of inverse discrete Fourier transform on in1. (Code is just like J() but sends ``1'' to fournp480 instead of ``-1''.)
Input:
- in1: a pvector
Add the above two operators to the definition of the pvector class.
Note: Along with L(), O(), I(), and J(), this completes the set
of operators needed to solve any set of non-linear, partial
differential equations with spatially local non-linear couplings.
This includes the Kohn-Sham equations of density-functional theory as
well as problems in fluid mechanics and a wide range of other problems
in the physics sciences.
