void check_ordered(const char *function, const char *name, const std::vector< T_y > &y)
Check if the specified vector is sorted into strictly increasing order.
Primary template class for the metaprogram to compute the index type of a container.
Definition: index_type.hpp:18
void domain_error(const char *function, const char *name, const T &y, const char *msg1, const char *msg2)
