eg
k = rand(10) > .4
STATS = regionprops(k, 'PixelList','PixelIdxList')

k is a binary image. Probably a poor name though. He made a 10x10 image using rand() and then thresholded it at 0.4 to create a binary image. Try this instead:
binaryImage = rand(10) > .4
STATS = regionprops(binaryImage, 'PixelList');
However you don't need regionprops to just find all the locations of white. You can just do
[rows, columns] = find(binaryImage)
