det()

float mrmeshpy.SymMatrix3d.det

(

self

)

computes determinant of the matrix

diagonal()

SymMatrix3d mrmeshpy.SymMatrix3d.diagonal ( float diagVal )

static

eigens()

Vector3d mrmeshpy.SymMatrix3d.eigens	(		self,
		Matrix3d	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()

Vector3d mrmeshpy.SymMatrix3d.eigenvector	(		self,
		float	eigenvalue )

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

identity()

SymMatrix3d mrmeshpy.SymMatrix3d.identity ( )

static

inverse() [1/2]

SymMatrix3d mrmeshpy.SymMatrix3d.inverse

(

self

)

computes inverse matrix

inverse() [2/2]

SymMatrix3d mrmeshpy.SymMatrix3d.inverse	(		self,
		float	det )

computes inverse matrix given determinant of this

normSq()

float mrmeshpy.SymMatrix3d.normSq

(

self

)

computes the squared norm of the matrix, which is equal to the sum of 9 squared elements

pseudoinverse()

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: unit normal to solution plane, rank=3: zero vector
