Declaring vectors

[vRltwE]

Hi,

I am declaring vectors in this way

    vector<vector<double> > matrix;
    matrix.resize(cols);
    for(int i = 0; i < cols; i++)
        matrix[i].resize(lines);

Is there a simple way I can setup the size of a matrix?

Some thing like

vector<vector<double> > matrix[lines][cols];

You can use constructors: vector< vector<double> > matrix( cols , vector<double>( lines ) );

Thanks Bazzy,

that was what I want.
