|
3373

793 \n\ |
|

794 Calling @code{error} also sets Octave's internal error state such that\n\ |

795 control will return to the top level without evaluating any more\n\ |

796 commands. This is useful for aborting from functions or scripts.\n\ |

800 example, given the following function definitions:\n\ |

|
809 \n\ |
|

|
810 @noindent\n\ |
|
|
811 calling the function @code{f} will result in a list of messages that\n\ |
|
|
812 can help you to quickly locate the exact location of the error:\n\ |

827 message but will not display any traceback messages as it returns\n\ |
|
|
828 control to the top level. For example, modifying the error message\n\ |
|

829 in the previous example to end in a new line causes Octave to only print\n\ |

830 a single message:\n\ |

832 @example\n\ |
