Thanks, that's helpful, but I forgot to mention that my graph is weighted.
In such case, I should create matrix_t with igraph_matrix_init, fill it with my weights, and create a graph using igraph_weighted_adjacency? (Is there any other option?)
Thanks,
Przemek.

There is no easy way, AFAIK. We could have a matrix view, that handles a chunk of memory as a dense matrix, and if the vector of vectors in C++ is a continuous chunk of memory, then there was an easy way.
But right now, just go over the matrix, put the non-zero edges in an igraph_vector_t and call igraph_create().

Dear all,
I know that igraph is written in C. However, what is the easiest way of creating an igraph graph from an adjacency matrix declared as a vector of vectors or from a list of links declared as a vector in C++?
Thanks,
Przemyslaw Grabowicz.
