Member Function/Subroutine Documentation

graph_clear()

final graph_mod::graph::graph_clear ( )

finalprivate

destructor

Definition at line 103 of file graph_mod.F90.

Here is the call graph for this function:

graph_create()

type(graph) function graph_mod::graph::graph_create ( integer, dimension(nl), intent(in)  nnz, integer, intent(in)  nl, integer, intent(in)  nc  )

private

Constructor for the type graph

Parameters

[out]	g	graph
[in]	nnz(i)	= number of non zero entries on line i
[in]	nl	= nulber of lines
[in]	nc	= nulber of columns if nc is unknown when creating the graph, set nc to 0 and reset it afterwards0
