The following equation can be used to compute values of y as a function of x: y = b  e?ax  sin(b  x)  (0:012  x4 ? 0:15  x3 + 0:075  x2 + 2:5  x) where a and b are parameters. Write the equation for implementation with MATLAB, where a = 2, b = 5, and x is a vector holding values from 0 to =24 in increments of x = =40. Employ the minimum number of periods (i.e., dot notation) so that your formulation yields a vector for y. In addition, compute the vector z = y2 where each element holds the square of each element of y. Combine x, y, and z into a matrix w, where each column holds one of the variables, and display w using the short g format. In addition, generate a labeled plot of y and z versus x. Include a legend on the plot (use help to understand how to do this). For y, use a 1:5-point, dashdotted red line with 14-point, red-edged white-faced pentagram-shaped markers. For z, use a standard-sized (i.e., default) solid blue line with standard-sized, blue-edged, green-faced square markers.

ENGR 1120 – PROGRAMMING FOR ENGINEERS (MATLAB) Homework Program #2 Objectives: Demonstrate knowledge of data files, vector variables, intrinsic functions, subscript manipulation, for loops, and plotting in MATLAB. You have been given a set of ASCII data files that contain directions for laying out patterns in a field. The data files contain in the first column a distance to travel and in the second column a direction heading. Unfortunately, the person who created the data did not have a good understanding of orienteering and the direction headings are given as referenced to a clock face. The pattern begins at the origin of a Cartesian coordinate system with the person facing 12 o’clock, see the figure below. The figure shows an example of the first step in the pattern being a distance of 1.5 feet in the direction of 7 o’clock. All direction headings are given in terms of this clock orientation. The distance values given are in feet. There are 5 data files provided online for testing of the program. Write a script file that will allow the user to input from the keyboard the filename of the file that they wish to analyze. Load only that ONE data file and plot the resulting pattern. Once each point forming the pattern has been located, find and designate on the plot which of the resulting nodes was the farthest away from the origin. Also find and designate the center of the pattern as defined to occur at the coordinate location corresponding to (average x, average y). When plotting the resulting pattern on the Cartesian coordinate system, set the axes limits to appropriate values. HINT: Correlate the direction headings provided in the data files to a Cartesian coordinate system by using the following vector in your script file. This requires subscript manipulation. angle = [60; 30; 0; 330; 300; 270; 240; 210; 180; 150; 120; 90] -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 1 2 3 4 5 6 7 8 9 10 11 12 you are here

EEGR 221 MATLAB Project 1 Basic Signals Fall 2015 Due date: 10/5/15 1. (a) Plot ?1(?) = ?(?+1)−?(?−5) where -7 < t < 7 seconds. Use millisecond units. (b) Plot ? = 5 ??? (??)[ ?(?+1)−?(?−5)] 2. (a) Plot x2(t) exactly as shown in this figure. Include the same titles and labels for the signal. Hint: Find the amplitude equations as function of time and insert those to your MATLAB script to create and plot this signal. (b) Decompose x2(t) into its even and odd components and plot x2e(t) and x2o(t). (c) Plot x2e(t) + x2o(t) and verify that x2e(t) + x2o(t) = x2(t). How to report the results?  For each plot you must label x and y axis and have a title for the plot. Following commands could be used. heaviside, plot, axis, ylabel, ylabel, title, fliplr, etc … At the command prompt of MATLAB you can type >> help [command name] to get help with any command.  Plot all of the signal for t between -7 and 7 seconds.  Save your commands in an m-file with your name in the name field. (e.g. John_Scott.m) and append the code to the end of your report.  Your report must be organized and your solution for each question mu st be clearly marked by the number of the question. Example 2.a or 2.b, … In each part the problem should be clearly identified. Type the problem statement in each section. Show the plots of input and output signals. Draw conclusions based on your plots and in problem 3 discuss why the property is not satisfied based on your plots.  Turn in a hard copy of your report in class. This report must include a cover page with the name of both student partners.

PlotCycloidArc(8.5) Math98 HW4 The cylcoid is the plane curve traced out by a point on a circle as the circle rolls without slipping on a straight line.1 In this exercise we will use MATLAB to create an animation of a circle rolling on a straight line, while a point on the circle traces the cycloid. a. Implement a MATLAB function of the form function PlotCycloidArc(ArcLength). This function takes in a positive number ArcLength and displays a snapshot of the cirle rolling (without slipping) on the x-axis while a point on the cirlce traces the cycloid. The circle is initially centered at (0,1) and has radius 1, and the initial tracing point is taken to be (0, 0). An example output is shown in the above ?gure. As in the ?gure, plot the cycloid arc black, the circle blue, and use a red dot for the tracing point. Hint: If the circle has rolled for a length of arc t = 0, the coordinates of the tracing point are (t-sin t, 1-cos t). b. Implement a MATLAB function of the form function CycloidMovie(NumHumps,NumIntervals). This function will output an animation of the circle rolling along a line while a point on the circle traces the cycloid. This function inputs two natural numbers NumHumps and NumIntervals representing the number of periods (or humps) of the cycloid and the number or frames per hump that will be used to make the animation, respectively. Use the getframe command to save frames outputted from PlotCycloidArc and the movie command to play them back together as a movie. Use the axis command to view the frames on the rectan- gle [0, 2pNumHumps] × [0, 5/2]. Also label the ticks 0, 2p, . . . , 2pNumHumps on the x axis with the strings 1See Wikipedia for more on the cycloid. 0, 2p, . . . , 2pNumHumps and do the same for 1, 2 on the y axis (see the ?gure above). Label the movie ’Cycloid Animation’. Submit MATLAB code for both parts a and b and a printout the ?gures obtained by the commands PlotCycloidArc(8.5), PlotCycloidArc(12), and CycloidMovie(3,10)
