bwmorph c-mex example

bwmorph_example converts the following example taken from the comment section of bwmorph.m to a c-mex file:

BW1 = imread('circles.png');
figure, imshow(BW1)
BW2 = bwmorph(BW1,'remove');
BW3 = bwmorph(BW1,'skel',Inf);
figure, imshow(BW2)
figure, imshow(BW3)

To create the dll, do the following at the MATLAB prompt:

>> mex -setup
(then pick any C/C++ compiler, such as lcc)
>> mex bwmorph_example.c

That's it. Now you are ready to use bwmorph_example as follows:

>> bwmorph_example

Three figures should appear on the screen (shown above), which are the same exact figures that appear when you run the example code directly from the MATLAB workspace.

The purpose of this submission is simply to show how to use these functions and get plots from within a c-mex file.
