2d vector declaration compile error

[skata]

I am using g++ on a sun OS machine and am getting a compile error when I declare this 2d array in the private member data of a class:

vector<double> c(0);
vector<vector <double> > mat(0, c);

matrix.h:43: 'vector' is used as a type, but is not defined as a type.
matrix.h:44: `vector' was not declared in this scope
matrix.h:44: syntax error before `>' token

Anyone know whats going on here?

This compiles for me.

vector<double> c;
vector< vector<double> > mat(0,c);

make sure you have the space between '>' '>'characters right?

vector< vector<double>[red]space[/red]> mat(0,c);

Include
#include <vector>
and
using namespace std;
and try again...

If you don't want to use

using namespace std;

you'll have to use

std::vector<double> c;
std::vector< std::vector<double> > mat(0,c);
