[请教]BCB与matlab的混合编程，com方法 出错

[mrdlovewlh]

各位高手，请教一个问题，我在学习BCB与matlab的混合编程，用的com方法，但是计算出的数据无法传出来，如下图所示，运行后提示错误，可能是这个函数用的不对，memcpy(outp,myout.parray->pvData,3*sizeof(double));
麻烦各位帮帮忙，先谢谢大家了！！
提示错误如下：
Project Project1.exe raised exception class EAccessViolation with message 'Access violation at address 00401c80 in module 'Project1.exe'.Read of address 0000001A' Process stopped. Use Step or Run to continue.

程序如下：
//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma link "add_OCX"
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::Button1Click(TObject *Sender)
{
double aa,bb,cc;
double src[2];
double outp[3];
SAFEARRAY InSafeArray;
TVariant data;
TVariant myout;
src[0]=0;
src[1]=1;
InSafeArray.cDims=1;
InSafeArray.fFeatures=FADF_AUTO;
InSafeArray.cbElements=sizeof(float);
InSafeArray.cLocks=1;
InSafeArray.rgsabound[0].cElements=2;
InSafeArray.pvData=src;
data.SetSAFEARRAY(&InSafeArray);
data.vt=VT_R8|VT_ARRAY;
addclass11->add(3,&myout,data);
memcpy(outp,myout.parray->pvData,3*sizeof(double));
aa=outp[0];
bb=outp[1];
cc=outp[2];
Edit1->Text=FloatToStr(aa);
}
//---------------------------------------------------------------------------

哦 谢谢妖哥 那请问该如何改正呢

看起来象是parray的值为NULL导致AV
