CUDA Thrust saxpy with placeholders and lambda expressions

Saxpy, namely z = a * x + y, is a very common operation to be performed in scientific programming. cuBLAS implements its own saxpy, but it is limited to the case when z = y, so in some circumstances it has to be implemented using a kernel function or using CUDA Thrust. On our GitHub website, a fully worked example is shown on how implementing saxpy in CUDA using Thrust and, in particular, using the placeholder technique. A fully worked example is also reported on how implementing saxpy ...
