ply_init_legFpt Subroutine

public subroutine ply_init_legFpt(maxPolyDegree, nIndeps, fpt, header, fft_flags)

Subroutine to initialize the fast polynomial transformation for Legendre expansion.

fpt%planPntToCheb = fftw_plan_r2r_1d( n = n, & & in = tmpIn, & & out = tmpOut, & & kind = FFTW_REDFT10, & & flags = planning_flags ) fpt%planPntToCheb = fftw_plan_r2r_1d( n = n, & & in = tmpIn, & & out = tmpOut, & & kind = FFTW_REDFT10, & & flags = planning_flags ) fpt%planChebToPnt = fftw_plan_r2r_1d( n = n, & & in = tmpIn, & & out = tmpOut, & & kind = FFTW_REDFT00, & & flags = planning_flags )

Arguments

Type	Intent	Optional	Attributes		Name
integer,	intent(in)			::	maxPolyDegree	Maximal polynomial degree for the transformation.
integer,	intent(in)			::	nIndeps	Number of independent values that can be computed simultaneously.
type(ply_legFpt_type),	intent(inout)			::	fpt	The Fast Polynomial Transformation setting to initialize.
type(ply_fpt_header_type),	intent(in)			::	header	Configuration settings for the projection.
integer,	intent(in),	optional		::	fft_flags	Planning flags for the FFT. Configuration to how much time to spend on finding an optimal FFT implementation in the FFTW. See: http://www.fftw.org/doc/Planner-Flags.html#Planner-Flags Defaults to FFTW_MEASURE.
