mlpack
Linear algebra utility functions, generally performed on matrices or vectors.
Definition: add_to_cli11.hpp:21
mlpack::kernel::LinearKernel
The simple linear kernel (dot product).
Definition: linear_kernel.hpp:32
prereqs.hpp
The core includes that mlpack expects; standard C++ includes and Armadillo.
mlpack::kernel::LinearKernel::serialize
void serialize(Archive &, const uint32_t)
Serialize the kernel (it has no members... do nothing).
Definition: linear_kernel.hpp:60
mlpack::kernel::LinearKernel::LinearKernel
LinearKernel()
This constructor does nothing; the linear kernel has no parameters to store.
Definition: linear_kernel.hpp:39
mlpack::kernel::LinearKernel::Evaluate
static double Evaluate(const VecTypeA &a, const VecTypeB &b)
Simple evaluation of the dot product.
