How to copy an array to vector

[devendert]

I need to copy the contents of 3d array to vector

_declspec(dllexport) void CallBrownianManagedAdapter(double*** myArray)
{
vector<vector<vector<double>>> myVector;
BrownianWrapper::BrownianBridgeAdapter objectBrownian;
array<double, 3>^ brownianArray = objectBrownian.CallingBrownianManagedCodeTemp();

}
myVector is 3D Managed array I need to copy it contents to Unmanaged Array or Vector which ever is easier. I appreciate your help.
