Important notices:Belangrike kennisgewings:

  • The list of those who qualify for test A3 can be found here. Die lys van diegene wat kwalifiseer vir A3 kan hier gevind word.
  • A3 is written in S207 on Tuesday, Nov 29, 9:00-11:00 (one group). Arrive early and remember to bring your student ID. If you qualify for extra time, please bring your official letter with you. A3 word geskryf in S207 op Dinsdag, 29 Nov, 9:00-11:00 (een groep). Kom vroeg en onthou om jou studentekaart te bring. As jy vir ekstra skryftyd kwalifiseer, bring jou amptelike brief saam.
  • According to the regulations of flexible assessment, A3 covers all material of the semester. Everything has equal weight. Scroll down for the 2014 and 2015 versions of A3, and now also the 2016 version of A2. Volgens die regulasies van buigsame assessering handel A3 oor al die werk van die semester. Al die onderwerpe dra gelyke gewig. Sien onder vir die 2014 en 2015 weergawes van A3, en nou ook die 2016 weergawe van A2.
  • The link to the SUNLearn Page has been updated. Those students who had trouble with access, please try it out and let us know. Die skakel na die SUNLearn Bladsy is opdateer. Daardie studente wie probleme gehad het, probeer asb en laat weet.

Hints for AssignmentsWenke vir Opdragte:

Common mistakes in assignments:Algemene Foute in Opdragte:

  • The document you hand in should show results (output). Just showing us your code is not good enough, we need to see its output. Missing output could be a misplaced semi-colon (;) that suppresses the output, or a Publish that failed. (In the latter case, we recommend that you watch the Publish video on SUNLearn.) Also, output will not appear if there were coding mistakes in earlier problems.
  • Use the template. (It is best to download using Google Chrome as Internet Explorer messes up the line breaks.)
  • You should use %%   to break up the questions in the script. (The space afterwards is important!)
    If you don't do this all results will appear at the end of publish and you will have missing figures.
  • Functions cannot be included in scripts. Save them in a different file and when publishing, include using type().
  • Do not use spaces in file or directory (folder) names.
  • File names should not start with numeric characters, only alphabetic.
  • Do not copy the output lines ans = ... from the command line to the publish script.
  • Turn off subplot when you are finished with it by typing subplot() (without input parameters).
  • Be sure to hand in the published version of your assignment, not the m-file.
    The m-file does not show the answers and figures, hence we cannot mark it.
    Maak seker om die gepubliseerde weergawe van jou opdrag in te handig, nie die m-lêer nie.
    Die m-lêer wys nie die antwoorde en figure nie so ons kan dit nie merk nie.
  • Seriously. Do not use spaces in file or directory (folder) names.

  • If you don't need help with your assignment
    you are under no obligation to attend the practical.
    As jy nie hulp met jou opdrag nodig het nie is jy
    onder geen verpligting om die prakties by te woon nie.
  • Lab etiquette: Before asking for help please try to find answers
    first on the lecture slides or SUNLearn videos.
    Lab maniere: Voordat jy vir hulp vra, probeer eers antwoorde kry
    op die lesingnotas of die SUNLearn videos.

MATLAB:MATLAB:

  • MATLAB can be purchased from MathWorks for around the price of a text book.
  • You must register an account at www.mathworks.com using your @sun.ac.za email address.
  • Then follow instructions at www.mathworks.com/store/link/products/student/new/
  • A second option is to try Octave. An open source (free) language with similar syntax to MATLAB.
    (Note, however, that all tests in this course will require the use of MATLAB.)
