The results of the Nachlausur can be found here.

You can have a look on your Klausur on Thursday, February, 19, between 11.00 and 13.00 o'clock in Arnimallee 6, room 131 (Secretary Nordt).

- The results of the Klausur can be found here.
The

**Klausur**takes place in the**ZIB lecture room**.Attention: for problem 4 on exercise 4, the method of Runge is not suitable, please use Runge-Kutta-4 instead. The corrected version of the exercise sheet can be found here. The presentation of problem 4 will be postponed to November, 25.

Attention: there is a mistake on exercise 1, in problem 3 entry \(a_{22} = -1\) not \(-1/25\), you can find the corrected version of the exercise sheet here.

There are now some Matlab programs to play around available on this homepage (see below).

## General Information

### Description

Extending basic knowledge on odes from Numerik I, we first concentrate on one-step methods for stiff and differential-algebraic systems and then discuss Hamiltonian systems. In the second part of the lecture we consider the iterative solution of large linear systems.

### Target Audience

Students of Bachelor and Master courses in Mathematics and of BMS

### Prerequisites:

Basics of calculus (Analysis I,II) linear algebra (Lineare Algebra I,II) and numerical analysis (Numerik I)

## Registration

All participants should register at the KVV, so that we know who is participating. The overall number of participants is also necessary to justify the equipment of the course. In addition, depending on your program of study, you have to register in the Campus Management.

## Exercises and Criteria for a Certificate

### Tutorial & Exercises

- The tutorial offers the possibility to discuss and better understand the presented material and exercises. Furthermore solutions of exercises are presented by the students.
- A sheet with exercises will be handed out each Tuesday during the lecture. These exercises are also available electronically on this web page (see below).
- The exercises are intended to be solved by teams of three members.
- The exercises consist of theoretical and numerical problems. The latter should be solved using Matlab (available at the students computer pool at the institute). Both types of exercises are rated seperately.
- The solutions have to be finished before the tutorial two weeks after they were handed out.
- The solutions of the numerical problems should be delivered by email to mawolf{at}math.fu-berlin.de. Note that a complete solution for a numerical experiment consists of a running Matlab code, a program executing the required test runs, and protocols of the execution of these test runs. Delivering a correct and running code without knowing what is going on in the code will be regarded and rated as attempt of deception.
- The solutions of the theoretical problems have to be presented in the tutorial on request (without regard to preference and presence) by a member of a given group.

### Klausur

- There will be a Klausur on 03.02.2015.
- Students who fail in the Klausur have a second chance in the Nachklausur, which will take place on 10.04.2015.

### Criteria for the Certificate

Neccessary and sufficient for a certificate are:

- written exam: passing the Klausur or the Nachklausur (the better grade counts)
- active participation: at least as much success as failure in the presentation of the solution of theoretical problems and 50% of the maximal number of points for numerical problems
- constant participation: 85% attendence in the tutorial (not checked)

Certificates are graded according to the result of the Klausur.

### Exercises

- exercise 1
- exercise 2
- exercise 3
- exercise 4
- exercise 5
- exercise 6
- exercise 7
- exercise 8
- exercise 9
- exercise 10
- exercise 11
