Description Jose Luis Blanco 2011-06-03 15:27:54 UTC
I found the following warnings (C4244) of __int64 being converted to int in three points. 
They don't harm but I guess it would be better to have a warning-clean build (if I make a patch to fix this I'll update this bug report):


 ColPivHouseholderQR(const MatrixType& matrix)
      : m_qr(matrix.rows(), matrix.cols()),
        m_hCoeffs(std::min(matrix.rows(),matrix.cols())),
        m_colsPermutation(matrix.cols()),
        m_colsTranspositions(matrix.cols()),
        m_temp(matrix.cols()),
        m_colSqNorms(matrix.cols()),
        m_isInitialized(false),
        m_usePrescribedThreshold(false)


  m_colsPermutation.setIdentity(cols);

    m_colsPermutation.applyTranspositionOnTheRight(k, m_colsTranspositions.coeff(k));
