template<typename VecType >

double mlpack::kernel::SphericalKernel::ConvolutionIntegral	(	const VecType &	a,
		const VecType &	b
	)			`[inline]`

Obtains the convolution integral [integral K(||x-a||)K(||b-x||)dx] for the two vectors.

In this case, because our simple example kernel has no internal parameters, we can declare the function static. For a more complex example which cannot be declared static, see the GaussianKernel, which stores an internal parameter.

Template Parameters:

VecType

Type of vector (arma::vec, arma::spvec should be expected).

Parameters:
