Write a MATLAB script file to integrate  using trapezoid method (do not use trapz command for this part, write your own script). Consider x=-0.5 to 3 with Δt=0.01, and compare your result with using “integral” and "trapz" commands (all in one file).

Using MATLAB or Octave, use documenting code to Write a script that prompts the user for a minimum and maximum real number, then generates and prints a random number in the requested range. The script should then do the same for an integer range. Sample output: Enter a minimum real value: 0.5 Enter a maximum real value: 30 A random number in the range ( 0.5000, 30.0000 ) is 1.7851 Enter a minimum integer value: -10 Enter a maximum integer...

Using MATLAB or Octave, Write a script that prompts the user for the coordinates of three points A, B, and C, namely (xA, yA), (xB, yB), (xC, yC), forming a triangle, storing each in a variable (for a total of 6 variables). The script should then calculate the centroid G = (xG, yG) using xG = xA+xB+xC 3 and yG = yA+yB+yC 3 , storing each in a variable. Finally, the script should print all four points. Sample output: Enter...
