To undrestand the main idea of convolutional neural networks, specially for the new comers to CNNs we made these codes small as it is possible and we added many comments in the codes almost each line has a comment.
the CNN in these codes is trained using ELM, and the local fields are independent from each other (no overlap).

and please if you used this toolbox ,cite my name in your paper.
for any referances , you can start with these ones that i used in my work:
