Sub Clone(ppSparse As MWSparse)

Creates a copy of an MWSparse object.

Parameters.

Argument Type Description

ppSparse MWSparse

Referencetoan

uninitialized

MWSparse

object to receive the

copy

Return Value. None.

Remarks.

Clone allocates a new MWSparse object and creates a deep copy

of the o bject’s contents. Call this function when a separate object is required

instead of a shared copy of an existing o bject refere nce.

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

0-12-1 0

00-1 2-1

000-1 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

ForI=1To4

rows(K) = I

cols(K) = I + 1
