  4. HW File MSWord Starting Point

  5. Consider an ARBITRARY Trapezoid HW00 P01 Trapezoid Area • The Area of this form is the AVERAGE OF THE BASE-LENGTHS times the HEIGHT • The ALGEBRAIC formula for the Area, A • a & b are BASE Lengths • h is the Height

  6. HW00 P01 Trapezoid Area • Ask user to enter a, b, h • Calc & Display Trapezoid area

  7. HW00 P03  Quadratic Eqn • Ask user to enter a, b, c for Quadratic Eqn shown below • DisplaySolution

  8. HW00 P07  CoSine City • Find Difference in MATLAB CoSineCalcs

  9. HW00 P11  Base Exposed • Plot This Function • Where • T  Temperature (°C) • t  time (minutes) • t0  = 3.3 minutes • For 1  t  9

  10. HW00 P15  SimuLink City • Solve the ODE below using the Icon Based Programming Environment, SimuLink

  11. HW00 P23 MuPAD Manipulation • For • Find UsingMuPAD

  12. HW00 P31  Excel Exposure • Compare Industrial Machine Tool Products from Gladiator Engineered Systems (GES) and the Competition Thru the use of an Excel RADAR Chart

  13. MATLAB provides a Very Nice Utility in which a Plot is sent to the MSWindows ClipBoard for Subsequent Pasting into Other Applications To Save to the ClipBoard Select Copy Options from the Edit menu. The Copying Options page of the Preferences dialog box appears. Complete the fields on the Copying Options page and click OK. Select Copy Figure from the Edit menu. Windows ClipBoard Copy

  14. Copy to Clipboard  Step-1 In Figure 1 Window Click Edit→Copy Options...

  15. Copy to Clipboard  Steps 2&3 In the Preferences Dialog Box check the Copy-Options Boxes as you see Fit Close the Dialog Box

  16. Copy to Clipboard – Steps 4&5 In the Figure Window use File → Copy Figure to send the plot to the clipboard Paste the plot image into PowerPoint, Word, etc.

  17. The Copy Figure export

  18. Copy SimuLink Model • A SimuLink Model

  19. The Copied Model

  26. Day1 demo Script

  27. DeskTop Recoveryto UnScramble the DeskTop

  28. All Done for Today Please TryUsingMATLAB • Let’s do MQ-00b

  29. A Trapezoid t h b • A = [Hgt] x [Avg-Width]

  30. >> fplot('cosh', [-2 2]) >> grid Cosh City

  31. 3x3 from ENGR43 • For The DC Linear Circuits We Will need to Solve Systems Of Algebraic Equations

  32. Example Problem 1-21 • Plot This Function Time For Live Demo • Where • T  Temperature (°C) • t  time (minutes) • For: 1  t  3

  33. Prob 1-21 >> t = [1:.01:3]; >> T = 6*log(t) - 7*exp(0.2*t); >> plot(t,T, 'LineWidth', 3) >> xlabel('t (Sec)') >> ylabel('T (deg C)') >> title('Temp vs time') >> grid

  34. Engr/Math/Physics 25 Appendix Bruce Mayer, PE Licensed Electrical & Mechanical EngineerBMayer@ChabotCollege.edu

  35. Example Demo Session >> %Use MATLAB As Calculator >> 17*19 ans = 323 >> 77/19 -4.3 ans = -0.2474 >> 64^(1/3) + 32^0.2 ans = 6 >> (7+11)*2.5 ans = 45 >> L = 14.4 L = 14.4000 >> W = 13.3 W = 13.3000 >> Area = L*W Area = 191.5200

  36. Prob 1-21 Command Script • From the Command Window >> t = [1:0.02:3]; >> T = 6*log(t) - 7*exp(0.2*t); >> plot(t,T), xlabel('time (min)'),ylabel('Temperature (°C)'), title('Problem 1-21'), grid

  37. Prob 1-22 Plot
