2.3 Long Lines
If you want to type a matlab command that is too long to fit on one
line, you can continue on to the next by ending with a space followed by
three full stops. For example, to type an expression with long variable
Final_Answer = BigMatrix(row_indices,column_indices) + ...
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 Pasting
Your windowing system's copy and paste facility can be used to enter
text into the matlab command line. For example all of matlab's built-
in commands have some helpful text that can by accessed by typing help
followed by the name of the command. Try typing help contour into
matlab 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 mouse
to select the example text and paste it into the command line. Try it
now and you should see a contour plot appear in the figure window.
