2020 set Octave's internal error state such that control will return to the\n\ | |
2021 top level without evaluating any more commands. This is useful for\n\ | |
2022 aborting from functions.\n\ | |
2023 \n\ | |

2025 the function calls leading to the usage message.\n\ | |

3373 | 2027 You should use this function for reporting problems errors that result\n\ |
2028 from an improper call to a function, such as calling a function with an\n\ | |
2029 incorrect number of arguments, or with arguments of the wrong type. For\n\ | |
2030 example, most functions distributed with Octave begin with code like\n\ | |
