How is the file cifar10-train.t7 organise?

[hainguyenct]

I downloaded the file cifar10-train.t7 for training. However, I do not know the structure of the file. The content of the file looks like:

I have some questions from this figure:

1. I do not know where is to show the labels (for example, airplane', 'automobile', 'bird'... as the code mentioned), which numbers in the matrix show labels?.
2. The file contains the information of 10,000 images, but, in this matrix, how to know identify the numbers which belong to the 1st image, 2nd image, 3rd image,...?
   Thank you very much in advance for your replies.
