Hi,
These kind of operations are supposed to be redirected to the generator,
for temporaries removal. This should be included in 1.6.0. I just need to
find some time to implement this.
It's essentially just a matter of calling
device_specific::matrix_axpy_template
template(device_specific::builtin_database::get(device));
device_specific::execute(template, statement, context)
At the right place.
