tutorial relies on deprecated functionnality (gko::lend)

[rbourgeois33]

The tutorial: https://github.com/ginkgo-project/ginkgo/wiki/Tutorial-2:-Implement:-Matrices

Relies on the use of the gko::lend function that is deprecated according to my compile output:

no longer necessary, just pass the object without lend [-Wdeprecated-declarations] 56 | generate_stencil_matrix(gko::lend(matrix));

As I declared my matrix with:
auto matrix = gko::share(mtx::create(exec, gko::dim<2>(discretization_points)));, should I use generate_stencil_matrix(matrix.get()); ?

same in https://github.com/ginkgo-project/ginkgo/wiki/Tutorial-3:-Implement:-Solvers

gko::stop::ResidualNormReduction<>::build() has to be replaced with:
gko::stop::ResidualNorm<>::build() .with_baseline(gko::stop::mode::initial_resnorm) ?
(and a ';' has to be added at the end of .on(exec))

finally, for the solve:
solver->apply(rhs.get(), u.get());

Or is there a more up to date tutorial somewhere ?

Thanks in advance,
Rémi

Hi @rbourgeois33 ,
All modification you mentioned should be correct.
Yes, our tutorial in wiki is quite outdate. We are working on new version of tutorial.
