MWSparse object has its own MWFlags property. This property overrides the

value of the any flags set on the object whose method’s are called.

Sub Clone(ppSparse As MWSparse)

Creates a copy of an MWSparse object.

Parameters.

Return Value.

None.

Remarks. Clone allocates a new MWSparse object and creates a deep copy of the

object’s contents. Call this function when a separate object is required instead

of a shared copy of an existing object reference.

Example. The following Visual Basic sample creates a 5-by-5 tridiagonal sparse

array with the following entries:

X = [ 2 -1 0 0 0

-1 2 -1 0 0

0 -1 2 -1 0

0 0 -1 2 -1

0 0 0 -1 2 ]

Sub foo()

Dim x As MWSparse

Dim rows(1 To 13) As Long

Dim cols(1 To 13) As Long

Dim vals(1 To 13) As Double

Dim I As Long, K As Long

On Error GoTo Handle_Error

K = 1

For I = 1 To 4

rows(K) = I

Argument Type Description

ppSparse MWSparse

Reference to an uninitialized

MWSparse object to receive the

copy.
