Lec #3Started 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. Other links to look at: The FORTRAN Programming Language Wikipedia Definition of FORTRAN Lec #4Continued 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. (To download programs, right click on link and “save link target as”. With one-button mouse use <ctrl><click> on link). On Athena to use these programs: ssh –X linerva.mit.edu To use the f90 compiler on Athena, use add sunsoft. Other sources of information: O’Reilly series of books on programming FORTRAN Resources - useful link with lots of information on FORTRAN in its various forms Lec #5Continued with FORTRAN. Character strings, control statements if and do; other commands such as include, common, parameter. More programs will be developed in class including simple output and computing root-mean-square scatter of randomly generated numbers. Lec #6Finish up FORTRAN. Compile, linking and runtime errors and miscellaneous topics. Practice with using the language. Lec #7Examines the changes that were made in FORTRAN90 with the introductions on more modern concepts in programming languages. |
