USPS Dataset with Class uint8

Hi, good day.

I am a total newbie with MATLAB and started to experiment on things. I got the USPS handwritten digits dataset from this site http://www.cs.nyu.edu/~roweis/data.html . After looking at the array's dimensions, it says that it is 256x1100x10 and class of uint8. I do understand that the last dimension represents the 10 digits (0-9) and the second column being the number of samples of each digit.

How do I interpret the first column? I am trying to figure out how to perform convolutional neural networks (image processing) which is why I needed to understand this.

Thanks alot!

256 because each image is 16*16 and the images have been converted into column vectors.
