HW 8
1. For this problem, set your Matlab path to use the angdiff function from the text toolbox, not the
Matlab toolbox. Use Matlab to write your own drivepoint program using the start given in class. Show
your code. Show a plot of the path for combinations in the table below. You will have 2 plots. Copy
plots from Matlab, paste into a Word document, and adjust size to fit the two plots to a line. Adjust
your axes using the following Matlab command:
axis([min(xpath(:))-0.1*abs(min(xpath(:))) ...
max(xpath(:))+0.1*abs(min(xpath(:))) ...
min(ypath(:))-0.1*abs(min(ypath(:))) ...
max(ypath (:))+0.1*abs(min(ypath (:)))])
a)
[xgoal ygoal] [xinit yinit angint]
[5 5] [3 5 pi]
[3 5 –pi+0.01]
b) Provide a complete explanation why the paths are different. It may help to print out some variables
the first time through the while loop.
c) Show a plot of the path for combinations in the table below. Copy plots from Matlab, paste into a
Word document, and adjust size to fit the two plots to a line. Adjust your axes using the command given
in part a:
[xgoal ygoal] [xinit yinit angint]
[5 5]
[8 5 –pi+0.01]
[8 5 0]
[8 5 pi/2]
[8 5 -pi/2]
[0 0]
[4 -3 pi/4]
[4 5 0]
[-2 -3 pi/2]
[3 -6 -pi/2]
