Classes
struct	stan::math::inv_sqrt_fun
	Structure to wrap 1 / sqrt(x) so that it can be vectorized. More...

Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.
namespace	stan::math
	Matrices and templated mathematical functions.

Functions
template<typename T , require_arithmetic_t< T > * = nullptr>
auto	stan::math::inv_sqrt (const T x)
template<typename Container , require_ad_container_t< Container > * = nullptr>
auto	stan::math::inv_sqrt (const Container &x)
	Return the elementwise 1 / sqrt(x)} of the specified argument, which may be a scalar or any Stan container of numeric scalars.
template<typename Container , require_not_var_matrix_t< Container > * = nullptr, require_container_bt< std::is_arithmetic, Container > * = nullptr>
auto	stan::math::inv_sqrt (const Container &x)
	Version of inv_sqrt() that accepts std::vectors, Eigen Matrix/Array objects or expressions, and containers of these.
