A script file is an external file that contains a sequence of MATLAB statements. By typing the filename, subsequent MATLAB input is obtained from the file. Script files have a filename extension of
.m and are often called M-files.
Scripts are the simplest kind of M-file. They are useful for automating blocks of MATLAB commands, such as computations you have to perform repeatedly from the command line. Scripts can operate on existing data in the workspace, or they can create new data on which to operate. Although scripts do not return output arguments, any variables that they create remain in the workspace so you can use them in further computations. In addition, scripts can produce graphical output using commands like
Scripts can contain any series of MATLAB statements. They require no declarations or begin/end delimiters.
Like any M-file, scripts can contain comments. Any text following a percent sign (
%) on a given line is comment text. Comments can appear on lines by themselves, or you can append them to the end of any executable line.
