3080 you may specify a list of variables and @code{load} will only extract\n\ |
|
|
3081 those variables with names that match. For example, to restore the\n\ |

3082 variables saved in the file @file{data}, use the command\n\ |

3090 \n\ |

3094 and a local symbol exists, the local symbol is moved to the global\n\ |

3095 symbol table and given the value from the file. Since it seems that\n\ |

3105 The @code{load} command can read data stored in Octave's text and\n\ |

3107 detect the type of file and do conversion from different floating point\n\ |
