Details

class GOffice.QuadMatrix

classmethod back_solvel(R, b, allow_degenerate)

Parameters:

• R (GOffice.QuadMatrixl) – An upper triangular matrix.

• b (GOffice.Quadl) – Input vector.

• allow_degenerate (bool) – If True, then degenerate dimensions are ignored other than being given a zero result. A degenerate dimension is one whose diagonal entry is zero.

Returns:

True on error.

This function solves the triangular system R*x=b.

x:

Result vector.

Return type:

(bool, x: GOffice.Quadl)
