Laboratory assignments

All lab material can be downloaded here.
Help and examination of the labs will take place via gitlab:
Gitlab helplist for TSBB08
Some help how to manage the gitlab helplist is shown in the end of this page.
Note that you need to refesh the gitlab helplist to see changes!


There are 2 rooms allocated for every lab, see the schedule in timeedit.
You can go there personally or you can log in remotely, see
Connecting to the University computer rooms
More specifically, here are the available computers: Computers
(We normally use Olympen, Asgård, Egypten and SU25 in this course.)

To start Matlab, in a terminal window, write:
module add prog/matlab

You can also use your own computer at home!
However, try to find a lab partner!

How to manage gitlab helplist

As mentioned above, help and examination of the labs will take place via gitlab:
Gitlab helplist for TSBB08
Note that you need to refesh the gitlab helplist to see changes!
What you should do is to create an issue where you provide your zoom address.
It will look approximately as shown below.

Ask for help/to present by submitting a "New Issue" as shown below:


Presentations and Help will be done via your personal zoom rooms. Please attach your zoom room number, as well as liu-ids. An example Issue can be seen below:


After that you have filled in all the stuff the arrows point at, the result could look like this:


Now just click on the colored "Create issue" button! Wait until one of the teachers handle your issue. While waiting you can continue with other lab exercises.
