Location: | Wegelerstraße 6 - Seminarraum 6.020 | |

6th floor, last room on right, heading southwest |

The contact person for tutorials is Sa Wu.

Admittance for oral exam based on homework assignments requiring

- 50% of points from theory assignments
- 50% of points from programming assignments

Day | Time | Room |
---|---|---|

Wednesday | 0830 – 1000 | 5.002, Wegelerstr. 6 |

Programming exercises will be based mainly in **Python**/**NumPy**/**matplotlib**.
Please send in your solutions to programming exercises via mail to your tutorial's teaching assistant.

This combination is a very useful for quick implementation. Algorithms can be put into code fast. Plots can be produced with little effort. Much of what is needed for the lecture can be found in the following examples.

Some Documentation and Tutorials can be found at the following links.- The Python Tutorial, Version 2.7.8
- NumPy Quickstart
- matplotlib tutorial

One easy way to obtain all necessary **Python** packages is Anaconda.

More installation alternatives, suggestions and instructions can be found on the websites for **NumPy** and **matplotlib**.

Model solutions are base on Python in version 2.7.8.
For editing and writing Python code, any good editor will do.
We recommend **Vim** or **Notepad++**.
