The ArrayElems(A) function returns a set of equations of the form (indices)=value specifying the values of the elements in Array A.

Only the elements that explicitly need to be specified, taking into account storage, are returned.  In the case of scalar storage, the appropriate special initializer format is returned instead of a set of equations.

This function is equivalent to op(3, A).

The ArrayNumElems(A) function returns the number of elements actually stored in Array A.

This ArrayNumElems(A, opt) function performs in the same manner, except that one of the following options may be specified.
