Function Documentation

create_kernel()

template<typename scalar_t >

std::unique_ptr<Kernel<scalar_t> > strumpack::kernel::create_kernel	(	KernelType	k,
		DenseMatrix< scalar_t > &	data,
		scalar_t	h,
		scalar_t	lambda,
		int	p = 1
	)

Creates a unique_ptr to a Kernel object, which can be GaussKernel, LaplaceKernel, ... .

Template Parameters

scalar_t

the scalar type to represent the kernel.

Parameters

k	Type of kernel
args	arguments to be passed through to the constructor of the actual kernel (fi, data, h, lambda for GaussKernel)

Returns

unique_ptr to a kernel

get_name()

std::string strumpack::kernel::get_name ( KernelType  k )

inline

Return a string with the name of the kernel type.

kernel_type()

KernelType strumpack::kernel::kernel_type ( const std::string &  k )

inline

Return a KernelType enum from a string. If the string is not recognized, a warning is printed and the GAUSS kernel type is returned.
