numImages is not the number of images in that folder, it's the length of the imageNames cell array. Though it's not really a cell array, it's just a single cell with the string holding the folder in the one and only cell. So the length is 1 cell, and numImages is 1. Please read the FAQ on cells and you will understand: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

So, assuming you fix that, you didn't give your error message. I don't see anything in your code where you tried to open a database. Please GIVE ALL THE RED TEXT . Don't snip or paraphrase like you did. We want it all, line numbers, traceback, code statements, everything .

OK now you edited it and it says

imageNames = ('D:\work\Databse');

so now imageNames is a 15 character long string that holds the name of the folder, so imageNames = 15 (characters). Probably not what you want.

Next are you sure you didn't misspell Database? In your string it's Databse.
