Stormy Attaway, in Matlab (Second Edition), 2012 1.2 The MATLAB Desktop Environment It assigns a value for the radius, and then calculates the area based on that radius. For example, we will now create a script called script1.m that calculates the area of a circle. The rules for file names are the same as for variables (they must start with a letter, after that there can be letters, digits, or the underscore). m is on the file name (this should be the default). When finished, save the file using File and then Save. To create a new script, simply type the sequence of statements (note that line numbers will appear on the left). (In earlier versions of MATLAB, click on File, then New, then M-file.) A new window will appear called the Editor. To create a script, click on File, then New, then Script. m extension).īefore creating a script, make sure the Current Folder (called “Current Directory” in earlier versions) is set to the folder in which you want to save your files.
The script can be executed, or run, by simply entering the name of the file (without the. The contents of a script can be displayed in the Command Window using the type command. In this book, we will reserve the use of the word “program” to mean a set of scripts and functions, as described briefly in Section 2.7 and then in more detail in Chapter 6.Ī script is a sequence of MATLAB instructions that is stored in an M-file and saved. However, the terms are somewhat loosely used by many people, and the documentation in MATLAB itself refers to scripts as programs. Therefore, the correct terminology is that these are scripts, not programs. These script files are interpreted, rather than compiled. MATLAB uses what are called either script files, or M-files (the reason for this is that the extension on the file name is.

The original program is called the source code, and the resulting executable program is called the object code.īy contrast, an interpreter goes through the code line-by-line, executing each command as it goes. A program that does this translation from a high-level language to an executable file is called a compiler. Programs that are written in high-level languages must therefore be translated into machine language before the computer can actually execute the sequence of instructions in the program. High-level languages have English-like commands and functions, such as “print this” or “if x < 5, do something.” The computer, however, can only interpret commands written in its machine language. To execute, or run, a program is to have the computer actually follow these instructions sequentially. A computer program is a sequence of instructions, in a given language, that accomplishes a task. Once a problem has been analyzed, and the algorithm for its solution has been written and refined, the problem is then written in a particular programming language.
