void check_row_index(const char *function, const char *name, const Eigen::Matrix< T_y, R, C > &y, size_t i)
Check if the specified index is a valid row of the matrix This check is 1-indexed by default...
void out_of_range(const char *function, int max, int index, const char *msg1="", const char *msg2="")
Throw an out_of_range exception with a consistently formatted message.
