Just a quickie (excuse the ignorance). Assuming all arrays have been
properly
dimensioned, are the following assignments legal:
y(row(1:nrows)) = sparse_y(1:nrows)
sparse_y(1:nrows) = y(row(1:nrows))
My language manual is not clear on what happens to the indirect
references
y(row(.)).
How does the efficiency compare to the corresponding loops
do i=1,nrows
y(row(i)) = sparse_y(i)
sparse_y(i) = y(row(i))
end do
Thank you!
