Constructor & Destructor Documentation

◆ Backward2D() [1/3]

plask::optical::modal::FFT::Backward2D::Backward2D ( )

Create uninitialized transform.

Definition at line 343 of file fftpack.cpp.

◆ Backward2D() [2/3]

plask::optical::modal::FFT::Backward2D::Backward2D ( Backward2D && old )

Move constructor.

Definition at line 345 of file fftpack.cpp.

◆ Backward2D() [3/3]

plask::optical::modal::FFT::Backward2D::Backward2D	(	std::size_t	strid,
		std::size_t	n1,
		std::size_t	n2,
		Symmetry	symmetry1,
		Symmetry	symmetry2,
		std::size_t	ld = `0`
	)

Init transform.

Parameters
