WebJun 1, 2015 · Update: First of all, the matrix of partial derivatives is just the representation of the derivative in the canonical basis. Therefore, it is natural to see this representation: it presents a nice way to do calculations with the derivative. WebThe Euler method is a first-order method, which means that the local error (error per step) is proportional to the square of the step size, and the global error (error at a given time) is proportional to the step size. The Euler method often serves as the basis to construct more complex methods, e.g., predictor–corrector method . surname stack
