Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

An Introduction to MATLAB: Running MATLAB (Macintosh)

Module by: Louis Scharf. E-mail the author

Note:

This module is part of the collection, A First Course in Electrical and Computer Engineering. The LaTeX source files for this collection were created using an optical character recognition technology, and because of this process there may be more errors than usual. Please contact us if you discover any errors.

In order to run MATLAB on a Macintosh SE or PLUS computer, you need the program called EDU-MATLAB. The program requires at least 1 Mbyte of memory, System 3.0 or above, Finder version 3.0 or above, and an 800K drive. A hard disc drive is highly recommended. In order to run MATLAB on a Macintosh II, IIx, IIcx, or SE/30SE/30, you need the program called MacII-MATLAB, and the same system requirements apply.

To start MATLAB, you may need to open the folder containing the MATLAB program. Then just “double-click” the program icon or the program name (for example, EDU-MATLAB). Figure A.1 shows a typical organization of the folder containing Mac II-MATLAB. It contains the main program, the settings file, the demonstrations folder, and any toolbox folders. The double-click on Mac II-MATLAB produces the Command window as shown in Figure A.2. You will also see a Graph window partially hidden behind it. (The fact that the window is not in ffont means that it is opened but not currently active.) If you do not know what “clicking,” “dragging,” “pop-up menu,” and “trash” mean, you should stop reading now and familiarize yourself with the Macintosh.

In the command window, you should see the prompt ≫≫. The program interpreter is waiting for you to enter instructions. At this point it is a good idea to run the demonstration programs that are available in the “About MATLAB” menu under the Apple menu. Just click on the “demos” button and select a demo. During pauses, strike any key to continue. Whenever you have a MATLAB file in any folder, then you may double-click the file to launch the program. This allows you to have your own folder containing your own MATLAB files, separated from the MATLAB folder.

MATLAB has four types of windows:

  1. Command for computing, programming, and designing input/output displays;
  2. Graph for displaying plots and graphs;
  3. Edit for creating and modifying your own files; and
  4. Help for getting on-line help and for running demos.

All windows follow the traditional behavior of Macintosh windows. You can resize them (actually the help window has a fixed size) or move them. For more details on menus and windows, see the Macintosh and MATLAB manuals.
