matlab simulation-Kalman filter and extended Kalman filter Recently, due to the need for graduation, I have learned and derived the Kalman filter and the extended Kalman filter (KF, EKF). I will make a record here. I will not make a theoretical derivation, but only a simulation record. 1. Kalman filter (1) Brief description of theory […]

[Relearning Python]: Python extended iterator
Write before Iterator First, let’s look at a way to check whether it is iterable: >>> hasattr(list,’__iter__’) True You can use the above method to check whether other default types of objects that have been learned, such as strings, lists, dictionaries, etc., are iterable. iter() is a special method that is the basis of iteration […]

[Java] Generics extends wildcard
We have already talked about the generic inheritance relationship before: Pair is not a subclass of Pair. Suppose we define Pair: public class Pair<T> {<!– –> … } Then, we wrote a static method for the Pair type, and the parameter type it receives is Pair: public class PairHelper {<!– –> static int add(Pair<Number> p) […]
[kubernetes] Use virtual-kubelet to extend k8s
1 What is virtual-kubelet? Kubelet is the agent of k8s, responsible for monitoring the scheduling of Pods and running Pods. The virtual-kubelet does not actually run on the host, but is a process that can run anywhere. This process pretends to be a real Node to k8s, but the actual operation can be customized. In […]
