Section 3 Files and File Management In using Matlab , you will read and write several types of fles , or collections of computer data. In this section, you will learn File management de±nitions and commands Saving and restoring information Script M-±les Errors and debugging Search path, path management, and startup 3.1 File Management Defnitions and Commands To describe ±le management, several concepts and de±nitions are introduced, then a few Unix commands are concisely described, followed by a description of Matlab commands in greater detail. File: A collection of computer data, either ASCII text or binary, that is stored on an external memory device, such as a disk or tape drive. The format of the ±le, or the order, size, and location

File System: The combination of hardware and software that allows ±les to be stored (written), retrieved (read), and managed. Structure of ±le system: The ±le system in Unix and MS Windows has a tree structure, with the base called the root, dividing sequentially into branches, called directories or folders. Files can be thought of as leaves along the branches. File types: For our purposes, there are two types of ±les: binary and text (also called ASCII text or plain text). Binary ±les contain both the machine instructions of executable programs and 37...
