Basics of MATLAB and Beyond

matlab will recall the last command that began with those characters.Subsequent use of ↑ will recall earlier commands that began with thosecharacters.2.3 Long LinesIf you want to type a matlab command that is too long to fit on oneline, you can continue on to the next by ending with a space followed bythree full stops. For example, to type an expression with long variablenames:Final_Answer = BigMatrix(row_indices,column_indices) + ...Another_vector*SomethingElse;Or to define a long text string:Mission = [’DSTO’’s objective is to give advice that’ ...’is professional, impartial and informed on the’ ...’application of science and technology that is best’ ...’suited to Australia’’s defence and security needs.’];2.4 Copying and PastingYour windowing system’s copy and paste facility can be used to entertext into the matlab command line. For example all of matlab’s builtincommands have some helpful text that can by accessed by typing helpfollowed by the name of the command. Try typing help contour intomatlab and you will see a description of how to create a contour plot.At the end of the help message is an example. You can use the mouseto select the example text and paste it into the command line. Try itnow and you should see a contour plot appear in the figure window.3 Matrices3.1 Typing MatricesTo type a matrix into matlab you must• begin with a square bracket [• separate elements in a row with commas or spaces• use a semicolon ; to separate rows• end the matrix with another square bracket ].For example type:c○ 2000 by CRC Press LLC
