Modules
module	fourier_space_oct_m

Data Types
type	fourier_space_oct_m::fourier_space_op_t

Functions/Subroutines
subroutine	fourier_space_oct_m::fourier_space_op_t_init (this, space, qq, cam, singularity)
	Initialise a Fourier space Op instance. More...
subroutine, public	fourier_space_oct_m::cube_function_alloc_fs (cube, cf, force_alloc)
	Allocates locally the Fourier space grid, if PFFT library is not used. Otherwise, it assigns the PFFT Fourier space grid to the cube Fourier space grid, via pointer. More...
subroutine, public	fourier_space_oct_m::cube_function_free_fs (cube, cf)
	Deallocates the Fourier space grid. More...
subroutine, public	fourier_space_oct_m::fourier_space_op_end (this)
subroutine, public	fourier_space_oct_m::dcube_function_rs2fs (cube, cf)
	The following routines convert the function between real space and Fourier space Note that the dimensions of the function in fs are different depending on whether f is real or complex, because the FFT representation is different (FFTW scheme). More...
subroutine, public	fourier_space_oct_m::dcube_function_fs2rs (cube, cf)
subroutine, public	fourier_space_oct_m::dfourier_space_op_init (this, cube, op, in_device, op_move)
	The operator can be provided either through op (which is copied) or through op_move (an allocatable that is taken over via move_alloc, avoiding a full-grid copy). Exactly one of the two must be present. More...
subroutine, public	fourier_space_oct_m::dfourier_space_op_apply (this, cube, cf)
	Applies a multiplication factor to the Fourier space grid. This is a local function. More...
subroutine, public	fourier_space_oct_m::zcube_function_rs2fs (cube, cf)
	The following routines convert the function between real space and Fourier space Note that the dimensions of the function in fs are different depending on whether f is real or complex, because the FFT representation is different (FFTW scheme). More...
subroutine, public	fourier_space_oct_m::zcube_function_fs2rs (cube, cf)
subroutine, public	fourier_space_oct_m::zfourier_space_op_init (this, cube, op, in_device, op_move)
	The operator can be provided either through op (which is copied) or through op_move (an allocatable that is taken over via move_alloc, avoiding a full-grid copy). Exactly one of the two must be present. More...
subroutine, public	fourier_space_oct_m::zfourier_space_op_apply (this, cube, cf)
	Applies a multiplication factor to the Fourier space grid. This is a local function. More...
