15. 15 Matlab basics: arrays

16. 16 Matlab basics: arrays++

17. 17 Matlab basics: arrays++

18. 18 Matlab basics: arrays++ Operations on arrays are much faster than for- loops!

21. 21 Assignment: implement Regula Falsi Explore the following problem (i.e. graphs, tables) and implement it in Matlab Exercise 1: Plot this function with 65 points on the given interval.

22. 22 Matlab basics: arrays++

23. 23 Matlab basics: functions

24. 24 Matlab: command window Command window Files in current folder Variables that are currently defined Editor

25. 25 Matlab: command window Command window Files in current folder Variables that are currently defined Editor ➊ ➋

26. 26 Matlab basics: functions

27. 27 Matlab basics: functions

28. 28 Matlab basics: functions

29. 29 Matlab basics: functions

30. Function can be Made as external m-file o Document/comment in-between steps o Function can have ‘side-effects’ (e.g. make a plot) o Suitable for functions that do “complex” operations  Check arguments  Need to use if/for etc Define inline o Short notation o Refer to coefficients in the current scope o Suitable for functions in mathematical sense.  Direct mapping of output to input 30 Matlab basics: functions

31. 31 Matlab basics: exercise 2

32. 32 Matlab basics: programming

33. 33 Matlab basics: programming

34. 34 Matlab basics: programming

35. 35 Matlab basics: programming

36. 36 Matlab basics: programming

37. CELL based editing o Collect commands rather than type them in command window o Adjust order, adjust form  E.g. plots you want to change title, labels, add elements iteratively o Execute small pieces of code rather than whole file o Code is publishable to a readable format 37 Matlab basics: programming

42. 42 Assignment: implement Regula Falsi Explore the following problem (i.e. graphs, tables) and implement it in Matlab Exercise 3: Implement REGULA FALSI in a cell based script. Write introduction with problem statement in LaTeX.

43. 43 Assignment: implement Regula Falsi (alt.) Explore the following problem (i.e. graphs, tables) and implement it in Matlab BONUS: Why is this formulation better?

44. 44 Sample implementation

45. Refer to an m-file as function object with @, e.g. fplot(@myfunc,[3,4]) Arguments are passed as copies, so changing the value of arguments inside a function does not change it outside of the function. Include m-files in published document with % myfunc.m 45 Addenda

46. Short Matlab introduction – Language basics – Programming concepts – Literate programming The assignments (2WN52) are to be implemented and handed in as a document published with Matlab. 46 Summary
