Hello everyone,
Is there an developer-intended way to view a Vector<double> object with dim
entries as a Tensor<1, dim> object for ease of multiplication with other
Tensor<1, dim> instances such as normal vectors?
I can do something like:
// dim = 3
Vector<double> vec({4,5,6});
ArrayView<double> view(&a[0], 3);
Tensor<1, 3, double> tensor(view);
but from the documentation this seems to make a copy, and I wondered if
there was a deal.ii way to "view" the Vector<double> as a Tensor object.
This operation is the result of a numerical flux computation and is called
many times during assembly.
Thank you,
Corbin
