Can anyone illustrate for me matrix decomposition in a simple way?
There are several types: LU-decomposition, QR- decomposition, and probably others.Can anyone illustrate for me matrix decomposition in a simple way?
It's the decomposition into a orthogonal rotation ##U## and a symmetric positive definite stretching ##P##, see the polar decomposition https://en.wikipedia.org/wiki/Polar_decompositionthank you for your responses, while i study elasticity it have been mentioned that deformation tensor is stretch and rotation tensor and the proof by using matrix decomposition, I've no idea about the type of decomp.
thank you too much, its helpful and valuable and easyIt's the decomposition into a orthogonal rotation ##U## and a symmetric positive definite stretching ##P##, see the polar decomposition https://en.wikipedia.org/wiki/Polar_decomposition
