void stan::math::check_unit_vector	(	const char *	function,
		const char *	name,
		const StdVec &	theta
	)

Throw an exception if the each element in a standard vector does not have unit Euclidiean length.

Template Parameters

StdVec

A standard vector with inner type inheriting from Eigen::EigenBase

Parameters

function	Function name (for error messages)
name	Variable name (for error messages)
theta	Vector to test

Exceptions

`std::invalid_argument`	if theta is a 0-vector
`std::domain_error`	if the vector is not a unit vector or if any element is NaN
