Lecture Notes

Special software is required to use some of the files in this section: .dat, .f, .m, .nb, and .tar. The .h files are header files.


LEC #TOPICSLECTURE NOTESNOTES, SUPPORTING FILES AND LINKS
1-2Introduction: problem formulation, algorithm development, algorithm implementation, and algorithm verification. Structure and documentation.

Lecture 1 (PDF)

Lecture 2 (PDF)



Lecture 1


Class introduction; overview of languages; program development



Lecture 2


Discussion of aspects of computers and their operation. An example is given of program development for a simple case of computing the area of a figure.

In the lecture notes the poly_area.f (F) FORTRAN program is referred to. This program implements the area determination algorithm discussed in the lecture.

Lecture 3


Started FORTRAN (Formula Translation). Went through the basic elements that make up this language. An on-line version of a FORTRAN 77 manual can be found here. In reading these notes, you should think about operations you want to do and what command or commands do you use to do that. The list on FORTRAN intrinsic functions can be found here.

Wikipedia Definition of FORTRAN



Lecture 4


Continued with showing the elements of the FORTRAN and more detail on the typically encountered features of the language. Topics covered: subroutines and functions; intrinsic functions; constants and variables; input output with open/close, read/write, formats; character strings.

The links in this lecture were to FORTRAN and intrinsic functions, which are given above. The programs poly_area.f (F) and vars.f (F) are also used.



Lecture 5


Continued with FORTRAN. Character strings, control statements if and do; other commands such as include, common, parameter.



Lecture 6


Finish up FORTRAN. Compile, linking and runtime errors and miscellaneous topics. Practice with using the language.



Lecture 7


Examines the changes that were made in FORTRAN 90 with the introductions on more modern concepts in programming languages.

8-11

C for scientific uses. Representation of data through arrays, pointers, and data structures. Function calls, argument passing and scoping rules, IO, profiling, system calls, and signals.

C++ objects. Encapsulation and inheritance, polymorphic operators.

Lecture 9


Continuation of C. Covering Examined C-pointer; file input/output and the routines for formatted reads and write; compiling C routines; the C preprocessor cpp; structures in C; memory management.

C++ class and program for a bouncing ball: Ball.h (H) and launch.cc (CC)

Example of overloading the + operator: coord.cc (CC) and coord.h (H)
