There is one prototype of asum
available, please see below.
asum( const VectorX& x );
asum (short for absolute
sum) provides a C++ interface to BLAS routines SASUM, DASUM, SCASUM,
and DZASUM.
The selection of the BLAS routine is done during compile-time, and is
determined by the type of values contained in type VectorX.
The type of values is obtained through the value_type
meta-function typename value_type<VectorX>::type. Table X below illustrates to
which specific routine this dispatching will take place.

The original routines SASUM, DASUM, SCASUM, and DZASUM have three arguments,
whereas asum requires
one arguments.
Defined in header boost/numeric/bindings/blas/level1/asum.hpp.
Parameters
