symmetricEigenvalues Method
Factor this matrix as a product U * lambda * UT where U is an orthogonal matrix and lambda
is a diagonal matrix.
- Note 1: You must apply this function to a
symmetricmatrix. Otherwise, the lower triangle is ignored and the upper triangle is mirrored to the lower triangle to enforce symmetry. - Note 2: This function is replaced by a faster method called
fastSymmetricEigenvaluesso consider using the fast version instead.
symmetricEigenvalues(leftEigenvectors: Matrix3d, lambda: Vector3d): boolean
| Parameter | Type | Description |
|---|---|---|
| leftEigenvectors | Matrix3d | a matrix that its columns will be filled by the left eigenvectors of this Matrix3d(allocated by caller, computed and filled by this function). Note that columns of leftEigenVectors will be mutually perpendicular because this matrix is symmetric. |
| lambda | Vector3d | a vector that its entries will be filled by eigenvalues of this Matrix3d (allocated bycaller, computed and filled by this function). |
Returns - boolean

- geometry3d/Matrix3d.ts Line 1076
