MATLAB: Do I receive unresolved symbol errors when trying to compile the MATLAB function using graphics

_mlfntitle_mlfnxlabel_mlfnylabelerrorexternallnk1120lnk2001MATLAB Compilersymbol [~]unresolved

I am trying to compile the following function:
function test_graphics_mcc( power )
x=-10:.1:10;
y=x.^power;
plot(x,y);
title(sprintf('x^%i',power));
xlabel('x');
ylabel('y');
I then compile it with the command:
mcc -t -L C -W libhg:test_graphics_mcclib -T link:lib test_graphics_mcc.m libmmfile.mlib libmwsglm.mlib
I receive the following errors: ERROR: test_graphics_mcc.obj .text: undefined reference to '_mlfNTitle' test_graphics_mcc.obj .text: undefined reference to '_mlfNXlabel' test_graphics_mcc.obj .text: undefined reference to '_mlfNYlabel'
   MBUILD.BAT: Error: Link of 'test_graphics_mcclib.dll' failed. 
 ??? Error using ==> mbuild
 Unable to complete successfully
 ??? Error: An error occurred while shelling out to mbuild (error code = 1).
 Unable to build executable (specify the -v option for more information).
 Error in ==> C:\MATLAB6p5\toolbox\compiler\mcc.dll

Using graphics in shared libraries is not supported.
The "-T link:lib" is what tells MCC to generate a shared library. You should generate only stand alone executables using graphics.
However, the actual error displayed is due to using Handle Graphics and a missing switch to MCC. Since you are using Handle Graphics, you need to use the "-B sgl" switch.
For more information, see:
https://www.mathworks.com/help/compiler/mcc.html
If you have already installed the help documentation for your licensed product(s), you may access the same page locally by typing the following at the MATLAB prompt:
web([docroot '/toolbox/compiler/mcc.html'])
From there:
 -B sgl (Stand-Alone C Graphics Library).   
 Produce a stand-alone C application that uses Handle Graphics. The -B sgl option is equivalent to the series of options -m -W mainhg libmwsglm.mlib
Here is the full command you should use:
mcc -B sgl -t -L C -W libhg:test_graphics_mcclib -T link:lib test_graphics_mcc.m libmmfile.mlib
However, remember that this is not supported, and you may run into other problems at a later time.
