Example of Test Driven Development with C++ and Google Test

To develop a software based on “Test Driven Development” one should follow the following steps:

so let say we want to develop a binary search tree,  here I’m using Google Test. Step 1, Write enough failing Test Code so the first step would be something like this:

Step 2, Write Production code to

Extended Kalman Filter Explained with Python Code

In the following code, I have implemented an Extended Kalman Filter for modeling the movement of a car with constant turn rate and velocity. The code is mainly based on this work (I did some bug fixing and some adaptation such that the code runs similar to the Kalman filter that I have earlier implemented).
