1 Creating a Sequence:\\

     2 {\ex \lstinline|   L = [0.1, 0.2, 0.3] |}

     3 

     4 Squaring a sequence:\\

     5 {\ex \lstinline|   tsquare=square(t) |}

     6 

     7 Plotting two list using small dots:\\

     8 {\ex \lstinline|    plot(L,tsquare,'.') |}

     9 

    10 Plotting two list using big dots:\\

    11 {\ex \lstinline|    plot(L,tsquare,'o') |}

    12 

    13 Plotting an errorbar in blue color:\\

    14 {\ex \lstinline|    errorbar(L,tsquare,xerr=delta_L, yerr=delta_T, fmt='b.') |}
