void igraph_arpack_options_init(igraph_arpack_options_t *o);
Initializes ARPACK options, set them to default values.
You can always pass the initialized
object to built-in igraph functions without any modification. The
built-in igraph functions modify the options to perform their
igraph_pagerank() always searches for the
eigenvalue with the largest magnitude, regardless of the supplied
If you want to implement your own function involving eigenvalue calculation using ARPACK, however, you will likely need to set up the fields for yourself.
Time complexity: O(1).
