ply_fpt_header_define Subroutine

public subroutine ply_fpt_header_define(me, blocksize, factor, approx_terms, implementation, striplen, subBlockingWidth, adapt_factor_pow2, lobattoPoints)

Define settings for the Fast Polynomial Transformation.

Arguments

Type	Intent	Optional	Attributes		Name
type(ply_fpt_header_type),	intent(out)			::	me	FPT header to hold the defined settings.
integer,	intent(in),	optional		::	blocksize	Blocksize to use in approximation algorithm. Defaults to ply_fpt_default_blocksize.
real(kind=rk),	intent(in),	optional		::	factor	Oversampling factor to use. This can be used to reduce aliasing when projecting functions that will be truncated in the polynomial series expansion. Default is a factor of 1, so no oversampling.
integer,	intent(in),	optional		::	approx_terms	Number of approximation terms to use for the representation of the blocks in the Legendre to Chebyshev transformation algorithm. Defaults to ply_fpt_default_approx_terms.
integer,	intent(in),	optional		::	implementation	Implementation to use in the computation. Select the implementation variant to use. Either scalar (ply_fpt_scalar) or vectorized (ply_fpt_vector). Default is ply_fpt_scalar.
integer,	intent(in),	optional		::	striplen	Length of strips to use in the transformation implementation. Defaults to vlen.
integer,	intent(in),	optional		::	subBlockingWidth	Width for subblocks in unrolling the approximate Legendre to Chebyshev transformation. Defaults to ply_fpt_default_subblockingWidth.
logical,	intent(in),	optional		::	adapt_factor_pow2	Adapt the oversampling factor such, that oversampled space has a number of degrees of freedoms in one direction that is a power of 2. Default is .false..
logical,	intent(in),	optional		::	lobattoPoints	Wether to use Chebyshev-Lobatto points (include boundary points) or not. Defaults to .false..
