bool check_ordered(const char *function, const char *name, const std::vector< T_y > &y)
Return true if the specified vector is sorted into strictly increasing order.
void domain_error(const char *function, const char *name, const T &y, const char *msg1, const char *msg2)
Throw a domain error with a consistently formatted message.
bool check_positive_ordered(const char *function, const char *name, const Eigen::Matrix< T_y, Eigen::Dynamic, 1 > &y)
Return true if the specified vector contains non-negative values and is sorted into strictly increasi...
