This example shows how MATLAB commands can be typed at the MATLAB prompt to plot a sine wave. Note that the diary file 'e1_diary' was used to store the commands typed as well as the MATLAB responses.
Commands Typed and MATLAB Responses:>> diary e1_diary >> amp = 3 amp = 3 >> freq_HZ = 5; >> freq_RPS = 2*pi*freq_HZ; >> t = 0:0.005:0.5; >> y = amp * sin(freq_RPS * t); >> plot(t,y) >> xlabel('Time (seconds)') >> ylabel('y(t)') >> title('EE341.01 Example 1 Plot') >> grid >> diary offResulting e1_diary Diary File:

The plot was printed by typing 'print' at the MATLAB prompt when the plot was displayed in the graphics window.
