Note that semicolons between numbers signify a new row.Īgain, spaces between numbers signify a new column, Note that spaces between numbers signify a new column. To create a variable, simply type the variable name at the prompt, followed the the equals sign (=), and followed by the initialization, as demonstrated below: To clear existing variables from memory enter the command clear at the prompt. To check to see what variables already exist and what dimensions they are, type the command whos at the prompt. If the variable already exists, MATLAB changes its contents and, if necessary, allocates new storage. When MATLAB encounters a new variable name, it automatically creates the variable and allocates the appropriate amount of storage. Unlike programming languages such as C or Java, MATLAB does not require any type declarations or dimension statements. Scalars and vectors can be used since they can be considered as matrices with dimension 1×1 (scalars) and 1xn or nx1 (vectors). All variables used are considered to be matrices.
MATLAB is designed to work with matrices, where a matrix is defined to be a rectangular array of numbers. To exit MATLAB, type exit or quit at the prompt.
To get help on a specific topic or function, type help at the prompt, replacing with the topic or function you wish to get help on. To get general MATLAB help, type help at the prompt to get a list of a help topics. For more information on UNIX commands, see the UNIX Documentation Page. The Command Window is where you will see a prompt that looks like >, and is where you will type in various commands.Īt the MATLAB prompt, you can run some basic UNIX commands such as cd and ls. The desktop consists of 3 windows: Workspace, Command History, and Command Window. Once MATLAB has started up, you will see the MATLAB desktop. Once you have logged into a windowing environment and have sourced the MATLAB setup files, you may start up MATLAB by typing matlab at the UNIX prompt.
