Details

class GOffice.QuadQR
classmethod determinantl(qr, det)
Parameters:
classmethod freel(qr)
Parameters:qr (GOffice.QuadQRl) –
classmethod mark_degeneratel(qr, i)
Parameters:
classmethod multiply_qtl(qr, x)
Parameters:
classmethod rl(qr)
Parameters:qr (GOffice.QuadQRl) –

determinant(det)
Parameters:det (GOffice.Quad) –
free()
multiply_qt(x)
Parameters:x (GOffice.Quad) – a vector.
Returns:a vector.
Return type:x: GOffice.Quad

Replaces x by Q^t * x

r()
Returns:the small R from the decomposition, i.e., a square matrix of size n. To get the large R, if needed, add m-n zero rows.
