array::section Method

  • Article

Returns a subsection of the array object that is at the specified origin and, optionally, that has the specified extent.

Parameters

  • _E0
    The most significant component of the extent of this section.

  • _E1
    The next-to-most-significant component of the extent of this section.

  • _E2
    The least significant component of the extent of this section.

  • _Ext
    The extent object that specifies the extent of the section. The origin is 0.

  • _Idx
    The index object that specifies the location of the origin. The subsection is the rest of the extent.

  • _I0
    The most significant component of the origin of this section.

  • _I1
    The next-to-most-significant component of the origin of this section.

  • _I2
    The least significant component of the origin of this section.

  • _Rank
    The rank of the section.

  • _Section_extent
    The extent object that specifies the extent of the section.

  • _Section_origin
    The index object that specifies the location of the origin.

  • _Value_type
    The data type of the elements that are copied.

Return Value

Returns a subsection of the array object that is at the specified origin and, optionally, that has the specified extent. When only the index object is specified, the subsection contains all elements in the associated grid that have indexes that are larger than the indexes of the elements in the index object.

Remarks

The overloads of this method let you create subsections of the array objects that have one, two, or three dimension.
