Details

class GOffice.QuadQR

classmethod determinantl(qr, det)

Parameters:

• qr (GOffice.QuadQRl) –

• det (GOffice.Quadl) –

classmethod freel(qr)

Parameters:

qr (GOffice.QuadQRl) –

classmethod multiply_qtl(qr, x)

Parameters:

• qr (GOffice.QuadQRl) – A QR decomposition.

• x (GOffice.Quadl) – a vector.

Returns:

a vector.

Return type:

x: GOffice.Quadl

Replaces x by Q^t * x

classmethod rl(qr)

Parameters:

qr (GOffice.QuadQRl) – A QR decomposition.

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.

Return type:

GOffice.QuadMatrixl

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.

Return type:

GOffice.QuadMatrix
