# Polar decomposition of a 3x3 matrix

3x3 SVD - 05/2018

Leaving [ C++ code ] to decompose a 3x3 matrix into rotation and scale/shear with polar decomposition.

(this is done through a 3x3 SVD and 3x3 Eigen decomposition).

Keywords:

- Polar decomposition of a 3x3 matrix
- 3x3 matrix SVD (Singular Value decomposition)
- Eigen decomposition (extract eigenvalues and eigenvectors) of a 3x3 matrix M (assumes symmetric matrix)
