template<typename EigMat , require_matrix_t< EigMat > * = nullptr>

void stan::math::check_pos_semidefinite ( const char *  function, const char *  name, const EigMat &  y  )

inline

Check if the specified matrix is positive definite.

Template Parameters

EigMat

A type derived from EigenBase with dynamic rows and columns

Parameters

function	Function name (for error messages)
name	Variable name (for error messages)
y	Matrix to test

Exceptions

<code>std::invalid_argument</code>	if the matrix is not square or if the matrix has 0 size.
<code>std::domain_error</code>	if the matrix is not symmetric, or if it is not positive semi-definite, or if any element of the matrix is NaN.
