Using the C Math Library

Specifying the Target Array

Each indexing function takes a target array as its first argument. The subscript is applied to this array:

• For mlfIndexRef(), the first argument is the array that you want to extract elements from.
• For mlfIndexAssign(), the first argument is the array that you want to change elements of (be assigned to).
• For mlfIndexDelete(), the first argument is the array that you want to delete elements from.

Note    mlfIndexRef() takes an mxArray*; mlfIndexAssign() and mlfIndexDelete() take mxArray** as their first argument.
