Vector Indexing Methods

VML mathematical functions work only with unit stride. To accommodate arrays with other increments, or more complicated indexing, you can gather the elements into a contiguous vector and then scatter them after the computation is complete.

VML uses the three following indexing methods to do this task:

The indexing method used in a particular function is indicated by the indexing modifier (see the description of the <mod> field in Function Naming Conventions). For more information on the indexing methods, see Vector Arguments in VML.
