回复： Re: some problems in using PETSC with FFTW3 package

[jiaxun hou <jiaxun_hou@xxxxxxxxxxxx>]

Satish,

Thanks for your response .

I am sorry for my confusing description. In fact , I did use the configure option

--with-scalar-type=complex when I configuated the system. So, I wonder if it is possible to change the type PetscScalar to some kinds like double[2] which can be handled in FFTW package? Or, is there any functions can get the real (imaginary) parts of a Petsc's Vector?

 

Regards,

Mason
