Detailed Description

symmetric 2x2 matrix Generated from class MR.SymMatrix2f. This is the const half of the class.

Member Function Documentation

pseudoinverse()

unsafe MR.SymMatrix2f MR.Const_SymMatrix2f.pseudoinverse ( float? tol = null, MR.Misc.InOut< int >? rank = null, MR.Misc.InOut< MR.Vector2f >? space = null )

inline

for not-degenerate matrix returns just inverse matrix, otherwise returns degenerate matrix, which performs inversion on not-kernel subspace;

Parameters

tol	relative epsilon-tolerance for too small number detection
rank	optional output for this matrix rank according to given tolerance
space	rank=1: unit direction of solution line, rank=2: zero vector Generated from method MR.SymMatrix2f.pseudoinverse. Parameter tol defaults to std.numeric_limits<float>::epsilon().
