There are multiple algorithms. For example, look up "flood fill"

For what? For how to use the imfill() function in the Image Processing Toolbox? Or for the source code that it uses?
To use it, you simply do
binaryImage = imfill(binaryImage, 'holes');
If you want to know at a low level what it does, you usually can't get that info since most toolbox m-files are just wrappers that pretty quickly jump into a DLL for which they don't supply source code. You can get similar code by searching on the internet.
If you want how they fill holes in a grayscale image, then Steve gives his source (a book) on this page: http://blogs.mathworks.com/steve/2007/07/26/filling-holes-in-images/
