I have recently started using Lapack++ which I found convenient for my programming purpose, in general.

Now, I need to solve a matrix using QR algorithm. I've searched the user manual and I found a LaGenQRFactComplex Class for the purpose. But it need a complex matrix type as input parameter (as per my understanding).

Is there any other way for me to use the same for solving a real valued matrix??
