Function/Subroutine Documentation

subroutine _qrm_compute_graph	(	type(_qrm_spmat_type)	qrm_mat,
		type(_qrm_spmat_type), intent(out)	graph
	)

Computes the adjacency graph of a matrix.

This subroutine computes the column graph associated to an input matrix qrm_mat COO format. The output graph has no duplicates as well as no self-edges

Parameters

[in]	qrm_mat	the input matrix
[out]	graph	the adjacenc graph in CSC format
