How to use QGenericMatrix for dynamic rows and columns?

Hi,

I need to create a matrix whose rows and columns are computed dynamically, so I need to create a matrix such as

Code:

---

int rows = calcRows();
int cols = calcCols();
QGenericMatrix<cols, rows, qreal> matrix;

---

But this will not compile because rows/cols are not constant. Is there a way to work around?

Thanks!

Not using QGenericMatrix class.
