Important Links#

• URM
• Alma

Exam dates#

The current decided timeslots for the oral exam can be found here. If you are not on this list but wish to be evaluated, please come to us and we will agree on a timeslot.

Registration#

• All students in examination regulations that are administered in Alma must register there both for the examination and for participation in the examinations. This concerns the following examination regulations: B.Sc. PO 2017 and 2019, B.Ed. Gymnasium PO 2016 and 2018, B.Ed. Vocational Schools PO 2015 and 2018, B.Ed. Preliminary Achievements Extension Subject PO 2019, M.Ed. Vocational Schools PO 2018, M.Ed. Extension Subject PO 2020. All information in this regard is without guarantee, in case of doubt check your exam regulations/module handbook .
• For students to be placed in the Übungalow, they must register in the URM for the Übungalow and indicate their scheduling preferences.

Lecture notes#

Here you can find some old lecture notes

• Numerics 2 (German version)

And here you will find the revised and slightly updated translation of each chapter

• FFT, Eigenvalue algorithms, CG, Iterative methods, Linear Optimization

Exercise sheets#

Here you can find the exercise sheets every Tuesday:

• Sheet 1
• Sheet 2
• Sheet 3
  • For Prog. Ex. 2: Input image, Convolution Matrix
• Sheet 4
• Sheet 5
• Sheet 6
• Sheet 7
• Sheet 8
  • For Prog. Ex. 7: Test Image
• Sheet 9
  • For Prog. Ex. 9 and 10: Matlab Code, Julia Code
• Sheet 10
• Sheet 11
• Sheet 12

Exercise classes#

• Every Tuesday, a new exercise sheet is published. You have one week to prepare the solutions.
• At the beginning of the exercise session, the participants tick the exercises they have solved. Tick the exercise only if you consider it to be meaningfully worked on and are able to present it without further preparation.
• In the event of illness, notify your tutor in advance and submit your work via mail.
• The tutor decides who is to demonstrate which task.
• If it becomes clear during the presentation that the exercise was not understood or contains major errors, all ticks of the relevant exercise sheet of the student will be scored as not ticked.
• In case of repetition, all exercises crossed in the semester by the student in question will be counted as unticked.

Programming exercises#

• In addition to the theoretical exercises, there will be regular programming exercises that are embedded in the regular exercise class. The programming exerciseses will thus also be discussed in the exercise class and will be evaluated as regular exerciseses. These are to be solved in Matlab or Julia.
• We would like to point out that enrolled students can obtain Matlab free of charge through the ZDV. If you have problems with the installation, please contact the ZDV.
• The programs are to be designed understandable and meaningfully commented.
• MathWorks interactive free video tutorials for students.

Schein allocation/Exam prerequisites#

• In order to be admitted to the exam, at least 50% of the exercises must be ticked.
• The exercises are composed of analytical and programming exercises.
• Prerequisite for a Schein is the passing of the exam.
• The presence in the exercise class and a active participation in the same are required.
