Question

So, what would be the C++ equivalent of f1.vector().array()? I.e., what C++ statement should I exactly use to obtain the underlying array of values from f1 (in the case of this example), presuming that f1 is a function, that has been used to store the solution from a solve statement?

Answer 1

You want Function::vector() to access the underlying vector, then you'll need to use get_local() on that to obtain the values (if the whole Function is owned by the process you are using these in).
