gp_exp_quad_cov() [3/7]

template<typename T_x , typename T_sigma , typename T_l >

Eigen::Matrix< return_type_t< T_x, T_sigma, T_l >, Eigen::Dynamic, Eigen::Dynamic > stan::math::gp_exp_quad_cov ( const std::vector< T_x > &  x, const T_sigma &  sigma, const T_l &  length_scale  )

inline

Returns a squared exponential kernel.

Template Parameters

T_x	type for each scalar
T_sigma	type of parameter sigma
T_l	type of parameter length scale

Parameters

x	std::vector of scalars that can be used in square distance. This function assumes each element of x is the same size.
sigma	marginal standard deviation or magnitude
length_scale	length scale

Returns

squared distance

Exceptions

std::domain_error

if sigma <= 0, l <= 0, or x is nan or infinite
