Question

Please help me with this MATLAB programming problem! Im coding iin MATLAB2018 if that makes any difference!

The first picture is the question i need to answer.

The picture below is used as reference to answer the question.

The last picture (below) is the into to the problem, and is used as reference.

1. Use Matlab to create the following single plot with three subplots. All titles, gridlines, and axis labels should be as shown. Arc System Response 15 E 05 0.5 10 time (sec) System Response position (m) 1.5F-velocity (ms) 0.5 0.5 10 time (sec) Notes: . Each subplot has a title. .Open the Matlab help on subplot to see how to get one plot to extend across two columns. The first subplot is an arc, centered at (1,1.5), with radius 2, extending from 459 to 180. Also plotted is asign at the center of the arc. Note that the axes are proportional (not squeezed more horizontally than vertically) and they extend at least 0.5 past where the circle containing the arc would be. The second is y 2 sin x, plotted from 0 to 10 with red dashed lines. Note the axis labels. The third is pos cos 2t and vel-2 sin 2t plotted across two columns. Note that there are axis labels, a legend, and the LineWidth of both plots has been set to 2 for better visibility Interacting with Plots: Run the script you used for part 0 to recreate that plot. At the Matlab command prompt enter ginput(1) and see what happens when you click on the plot. That should give you some ideas. What if you wanted to be able to put a point on a plot by hand? Add the following lines to the end of your test script: hold on; x,y) ginput (1) plot (x,y,'+' What if you wanted to add some text to your plot by hand? Add the following two lines to the end of your test script: hold on x,y ginput (1) text (x,y, 'My Text Comment) What if the third line above were text (x, y, 'My Text Comment', 'Colorcyan)? You can retrieve a third value from the ginput function. That third value is the mouse button the user pressed. The Matlab help has more details, but button 1 is the left button, button 3 is the right button, and on some hardware, button 2 is the middle button or scroll wheel button. Try x, y ginput (2) plot (x,y,'- Matlab Plotting Intro: 0. Practice: Write a short test script to use Matlab to plot a line from point (2,1) to point (10,2) Experiment with grid on/off, box on/off, and axis on/off Change the color, line style, and data markers for the line Use axis equal to set the scaling for each axis to the same spacing Know how to change the thickness of a curve's line, using the keyword-value pairs both from the plot command and using the set command. Recall that 'Linewidth' is the keyword of interest for this feature Look at your plot and consider what it is showing you. With axis equal still enabled, change the limits of the x-axis to go from 0 to 11. Does that make it more or less clear that you have drawn a line segment and not part of a larger curve? Use the command line to see what clf (clear figure) does If you try to plot a second line between two different points with another plot command, what happens to the first line? Experiment with hold on and hold off to understand how they work.

Answer 1

Code:

clc % subplot of Arc xpoint - 1; ypoint - 1.5; rad - 2; Cb-deg2rad (180); Ca deg2rad(45); theta - Ca:pi/50:cb; al - xpoint + rad * cos(theta); bl - ypoint + rad * sin (theta); %subplot for first plot subplot (2, 2, 1) plot(al, b1, 'b'); ylim([-1 4]); xlim([-1 3]); hold on plot(1, 1.5, '+r') title( 'Arc') grid on hold off %subplot of System Response p 0:0.5:10; q2*sin(p); subplot (2, 2, 2); plot(p, q, "--r'); ylabel('response(m)') xlabel('time(sec)') title('System Response') grid on

Subplot of System Response te:pi/5e:2*pi; V2*sin(t*2) pcos(t*2); subplot(2, 2, 3) plot(t, p, "--b', "Linewidth', 2) hold on plot (t, v, "--m', 'Linewidth', 2) ylabel('response (m or m/s)') xlabel('time (sec)') title( 'System Response') legend position (m)', 'velocity (m/s)', Location', northwest', orientation', 'vertical') grid on hold off
