Member Function Documentation

void clipper::FFTmap_sparse_p1_base::init	(	const Grid_sampling &	grid_sam,
		const FFTtype	type = Default
	)

initialiser: takes grid

Initialise an FFTmap_sparse_p1_base for a grid.

Parameters:

grid_sam	The grid sampling of the unit cell.
type	Can be FFTmap_sparse_base::Measure, ::Estimate. Measure performs slow precalculation (first time only) to get faster FFT.

Reimplemented in clipper::FFTmap_sparse_p1_hx, and clipper::FFTmap_sparse_p1_xh.
