template<typename T_y >
bool stan::math::is_corr_matrix (const Eigen::Matrix< T_y, Eigen::Dynamic, Eigen::Dynamic > &y)
 Return true if the matrix is square and not 0x0, if the matrix is symmetric, diagonals are near 1, positive definite, and no elements are NaN A valid correlation matrix is symmetric, has a unit diagonal (all 1 values), and has all values between -1 and 1 (inclusive). More...
