1 Creating a linear array:\\

     1 Creating a string:\\

     2 {\ex \lstinline|    x = linspace(0, 2*pi, 50)|}

     2 {\ex \lstinline|    s = ``Hello World''|} -- Single quotes and triple

     3 quotes can also be used.  

     4 Plotting two variables:\\

     5 Accessing individual elements:\\

     5 {\ex \lstinline|    plot(x, sin(x))|}

     6 {\ex \lstinline|   s[5]|} -- Elements can be accessed with their index

     7 Plotting two lists of equal length x, y:\\

     8 Strings are immutable.
