My Simulink model:
Is it possible to print this graph without scope (in matlab code)?
Yes, you can save the data to the workspace using a To Workspace block and plot it after the simulation has finished using standard MATLAB code. Plenty more options in the doc under Visualize Results.
Rightklick on a Signal->Create connected viewer->Floating scope.
If you need more advanced techniques, check the documentation examples about signal logging and signal inspection.

I would like to use the Autonomous Driving Toolbox in Matlab. But I prefer to know more abou it before I buy it. For instance, is it possible to customize some modules in the toolbox with some different algorithms than the default? For example, in the motion planning section of the toolbox, there's only one planner module provided by Matlab called "pathPlannerRRT" which implements the RRT algorithm for path planning, is it possible to create another customized planner with another or self-designed algorithm?

When i run my simulink model, the scope gives me correct graph but it disapears. It only the time 9-10 is shown on plot. Can anyone help to represent the graph.
Thanks
By default, only the last 5000 data points are plotted on the scope. You almost certainly have 50000 simulation steps from 0-10s and hence are only seeing the 5000 points from 9-10s.
Use the zoom controls on the scope to view all the points after simulation, or change the scope properties to change how they appear during simulation. How to do that is different in different versions of Simulink, but should be relatively easy for you to find.

I surf the web for HOF implementation in matlab or openCV. Actually I wanted to know how to write their code in matlab. I learned something from the link bellow about HOG but I cannot find the same proper link for HOF or MBH. Is there any syntax for HOF in openCV?

I dont know about OpenCV, but find matlab implementations here.

Since MATLAB is not good with loop, I am putting some of the looping into a c-dll(visual studio 6.0).
What do I have to do in building the c-dll that is different than
normal dlls?
How do I interface with the DLL from MATLAB?
I recommend making them into MEX-functions. Read the MATLAB help: http://www.mathworks.co.uk/help/techdoc/matlab_external/f29322.html.
And FWIW, MATLAB's fine at looping if you write your code well.

how to retrieve the data from m.file into another m.file?
How to compare these two files?
Referring to these posts matlab comes with a diff tool on board, offering an API.
com.mathworks.mde.difftool.DiffReportGroup.getInstance.showFileDiff(...
filePathLeft, filePathRight, numColumns);
showUnsavedChangesDiff(filePathLeft,textString,numColumns)
See the referred posts for further details.
