Is it possible to use C++ string and sstream in MATLAB MEX?

Dear All,

Is it possible to use C++ string and sstream in a MATLAB MEX file? The following is a part of my code in which I am having problem:

string VariableNames;
ostringstream strout( VariableNames );
strout << "x y z "; 
for( int i = 0; i<N; i++)		
	strout << GetComponentName( i ) << " ";		
VariableNames = strout.str();

Although I have included string and sstream header files, MATLAB complains with the following error message:

 error C2065: 'string' : undeclared identifier

Could someone tell me if using C++ string is usable in MEX.

Did you

#include <string>

You probably also need to add "using namespace std;", and ensure that your MEX-file has a .cpp extension.

Thanks @Kaustubha. Excellent catch. namespace was the problem.
