    Dear Karli,

    I am woundering if it would be possible to run a QR decomposition of a compressed matrix (i only saw that you did it for dense matrix)

    Best regards,

    Olivier

    Hi Olivier,

    ViennaCL does not provide a QR decomposition of sparse matrices. Such algorithms are hard to parallelize well (and possibly impossible to parallelize on GPUs). I recommend 'standard' CPU-based linear algebra libraries for this.

    Best regards,
    Karli
