How to read the structure of a neural network in a mat file?

Hi,

I have a mat file which is a neural network, and I want to know the structure of the network. I tried to open the mat file in Matlab, and there are two variables layers and meta. If I typed meta, I can only see the word 1x1 struct as below:-

    meta = 

           inputs: [1x1 struct]
          classes: [1x1 struct]
    normalization: [1x1 struct]

If I typed layers, I can only see the below,

    layers = 

      Columns 1 through 7
        [1x1 struct]    [1x1 struct]    [1x1 struct]    [1x1 struct]    [1x1 struct]    [1x1 struct]    [1x1 struct]

How can I see the information of meta and layers? Besides, is it possible to have any other hiding variables in the mat file apart from meta and layers?

Many thanks!

Can you provide the .mat model file?
