Programming • 'tn MA T LAB: Scripts and • Functions A distinguishing feature of MATLAB is its ease of extendability through userwritten programs. MATLAB provides its own language, which incorporates many features from C. In some regards, it is a higher-level language than most common programming languages, such as Pascal, Fortran, and C, meaning that you will spend less time worrying about formalisms and syntax. For the most part, MATLAB's language feels somewhat natural. In MATLAB you write your programs in M-files. M-files are ordinary ASCII text files written in MATLAB's language. They are called M-files because they must have a .m at the end of their name (like myfu nction.m). M-files can be created using any editor or word processing application. There are two types of M-files-script files and function files. We will now discuss their purpose and syntax. 4.1 Script Files A script file is an M-file with a set of valid MATLAB commands in it. A script file is executed by typing the name of the file (without the .m extension) on the command line. It is equivalent to typing all the commands stored in the script file, one by one, at the MATLAB prompt. Naturally, script files work on global variables, that is, variables currently present in the workspace. Results obtained from executing script files are left in the workspace.
