Question

I have this function:

    void RegMatrix::MatrixInit(int numRow,int numCol, std::vector<double> fill)

    {

      do something;

    }

and i want to send this:

MatrixInit(numRow,numCol,NULL);

how can i pass NULL as vector?

Answer 1

You cannot pass NULL as vector, you could instead pass an empty vector like this:

MatrixInit( numRow, numCol, std::vector<double>() )

Note that you would be better off taking the fill vector as const&.
