static

eigens()

Vector2f meshlib.mrmeshpy.SymMatrix2f.eigens	(		self,
		Matrix2f	eigenvectors = None )

returns eigenvalues of the matrix in ascending order (diagonal matrix L), and
optionally returns corresponding unit eigenvectors in the rows of orthogonal matrix V,
M*V^T = V^T*L; M = V^T*L*V

eigenvector()

Vector2f meshlib.mrmeshpy.SymMatrix2f.eigenvector	(		self,
		float	eigenvalue )

computes not-unit eigenvector corresponding to a not-repeating eigenvalue

identity()

SymMatrix2f meshlib.mrmeshpy.SymMatrix2f.identity ( )

static

inverse() [1/2]

SymMatrix2f meshlib.mrmeshpy.SymMatrix2f.inverse

(

self

)

computes inverse matrix

inverse() [2/2]

SymMatrix2f meshlib.mrmeshpy.SymMatrix2f.inverse	(		self,
		float	det )

computes inverse matrix given determinant of this

maxEigenvector()

Vector2f meshlib.mrmeshpy.SymMatrix2f.maxEigenvector

(

self

)

computes not-unit eigenvector corresponding to maximum eigenvalue

normSq()

float meshlib.mrmeshpy.SymMatrix2f.normSq

(

self

)

computes the squared norm of the matrix, which is equal to the sum of 4 squared elements

		Vector2f	space = None )

for not-degenerate matrix returns just inverse matrix, otherwise
returns degenerate matrix, which performs inversion on not-kernel subspace;
\\param tol relative epsilon-tolerance for too small number detection
\\param rank optional output for this matrix rank according to given tolerance
\\param space rank=1: unit direction of solution line, rank=2: zero vector
