In this section, we discuss the theory and implementation of Euler’s method in matlab. Leonhard Euler was born in 1707, Basel, Switzerland and passed away in 1783, Saint Petersburg, Russia. In 1738, he became almost blind in his right eye.It is worth to be nitpicking: % x0 is the initial guess. No, x0 is the initial value of the trajectory when you consider the integration. To solve a boundary value problem, you need an additional layer around the integration: e.g. a single shooting or multiple shooting method.4. At first you would have to subtract vector one from vector two in order to get vector two relative to vector one. With these values you can calculate Euler angles. To understand the calculation from vector to Euler intuitively, lets imagine a sphere with the radius of 1 and the origin at its center.
