19 | ; @keyword COUNT {type=vector} |
---|
20 | ; An optional vector containing the counts to be used in |

21 | ; reading Value. COUNT is a 1-based vector with an element for |
---|
22 | ; each dimension of the data to be written.The default matches |

23 | ; the size of the variable so that all data is written out. |

25 | ; @keyword GROUP |
---|
26 | ; The widget ID of the widget that calls XNCDF_LEC. When |

33 | ; |
---|
34 | ; @keyword SHIFT {type=vector}{default=[0, 0,...]} |
---|
35 | ; A vector of integers, specifying for each dimension how much we have to shift it. |
---|
36 | ; By default, it is [0,0,...]. See the function <proidl>shift</proidl> for more explanations. BEWARE, |
---|
37 | ; the shift is done on the biggest array before a possible reduction determined |
---|
38 | ; by OFFSET and COUNT. On the other hand, it is done after the possible extraction |

39 | ; created by the STRIDE. |
