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
|
result
|
|
|
|
|
All
|
size of the Array as specified by its bounds
|
|
Stored
|
number of entries actually stored
|
|
NonZero
|
number of non-zero elements of the Array
|
|
NonZeroStored
|
number of stored non-zero elements of the Array
|
|
Bytes
|
number of bytes of storage allocated for data in the Array
|
|
Allocated
|
number of elements for which storage has been allocated
