5098 Save the data in HDF5 format but only using single precision.\n\ |

5099 You should use this format only if you know that all the\n\ |

5100 values to be saved can be represented in single precision.\n\ |

5103 Force Octave to save the values of built-in variables too. By default,\n\ |

5104 Octave does not save built-in variables.\n\ |

5110 @item ?\n\ |

5115 \n\ |
|

5116 @item [ @var{list} ]\n\ |
|
|
5117 Match the list of characters specified by @var{list}. If the first\n\ |
|
|
5118 character is @code{!} or @code{^}, match all characters except those\n\ |
|
|
5119 specified by @var{list}. For example, the pattern @samp{[a-zA-Z]} will\n\ |
|
|
5120 match all lower and upper case alphabetic characters. \n\ |

5123 Except when using the @sc{Matlab} binary data file format, saving global\n\ |

5124 variables also saves the global status of the variable, so that if it is\n\ |

5125 restored at a later time using @samp{load}, it will be restored as a\n\ |

5126 global variable.\n\ |
