type(SpMtx) SpMtx_distribution_mod::SpMtx_exchange	(	type(SpMtx),intent(in)	A,
		type(indlist),dimension(:),intent(in)	sends,
		type(Mesh),intent(in)	M,
		integer,dimension(:),intent(in)	lgi,
		integer,dimension(:),intent(in)	lgj
	)

Exchange matrix elements between all processes and store into the new matrix.

Parameters:

A	matrix, which elements are to be sent
sends	indices of matrix elements to send to each neighbour
M	mesh that contains neighbour info
lgi	local to global for A row indices
lgj	local to global for A column indices
