cotanWeights()

template<typename T , class TriangulationType = AbstractTriangulation, typename SparseMatrixType >

int ttk::Laplacian::cotanWeights	(	SparseMatrixType &	output,
		const Debug &	dbg,
		const TriangulationType &	triangulation
	)

Compute the Laplacian matrix of the graph using the cotangente weights method.

Parameters

[out]	output	Laplacian matrix
[in]	dbg	Debug instance
[in]	triangulation	Access to neighbor vertices, should be already preprocessed

Returns

0 in case of success

	)

Compute the Laplacian matrix of the graph.

Parameters

[out]	output	Laplacian matrix
[in]	dbg	Debug instance
