Converting managed array to unmanged

CLI

I am trying to expose a Managed Function to Unmanaged Code using C++/CLI wrapper

public:array<double, 3>^ CallingBrownianManagedCodeTemp()
{
   int numPaths = 100;
   int dimension = 3;
   double time = 30;
   int seed = 1;
   double stepSize = 1.0 / 12.0;
   int scrambling = 0;
   array<double, 2>^ covMatrix = { { 1.0, 0.0, 0.0 },							 { 0.0, 1.0, 0.0 },							 { 0.0, 0.0, 1.0 } };		   
   std::string str = "Sobol";
   String^ newSystemString = gcnew String(str.c_str());
			   			   
   array<double, 3>^ result = (array<double, 3>^)    IAModel::RandomNumberGenerator::iBrownianBridge(numPaths, dimension, time, seed, covMatrix, stepSize, newSystemString, scrambling);
			   
return result;
}

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

I need to copy the contents of brownianArray (Managed Array Dynamic) to Unmanaged array which is myarray. I do not mind vector also. I was trying to declare a vector but the program won't recognize the vector in CLI.

I am new to C++, appreciate any suggestion

What I have tried:

stackoverflow.

It works in C#
