Description
|
|
•
|
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.
|
opt
|

|
