find_blocks()

std::vector< std::vector< int > > nda::find_blocks	(	nda::matrix_view< double >	m,
		double	threshold
	)

Find a block structure of a Matrix.

Parameters

m	A matrix (typically abs(some_matrix)).
threshold	Any value below this threshold is considered as 0

Returns

List of the groups of rows/cols which would make the matrix block diagonal
