Web-Oriented Sources Dealing With MATLAB

• The "source": The Mathworks. The company that makes MATLAB has a wide range of information, technical notes and resources. There is a "MATLAB in Education" area that may be of interest. The link to the "Homework Helper" may or may not be useful to you but you do get to see pictures of happy students whose lives have been changed once they started using MATLAB.
  
  
• The newsgroup comp.soft-sys.matlab is on on-line forum dedicated to using and improving MATLAB. Ask (serious) questions there and you will usually get fast, complete and accuracte answers. You can read this newgroups through many places (Google News is a good one) and the Mathworks has been good enough to provide a simple web-based reader for following the group.
  
  
• There are any number of sites (somewhat like this one) that purport let you know how to use MATLAB either in a tutorial fashion or in some specific, problem-oriented fashion (e.g., signal processing, optimization, etc.). Try a Google (or whatever search engine you prefer) search with "MATLAB" and "tutorial" or "MATLAB" and "topic". There are lots of people who use MATLAB for education and for their professional life.
