How to know where a class and its members are located ?

How do I locate where this file / function is ? dagnn

% Add softmax loss layer.
pFc8 = (arrayfun(@(a) strcmp(a.name, 'predcls'), net.layers)==1);
net.addLayer('losscls',dagnn.Loss(), ...
  {net.layers(pFc8).outputs{1},'label'}, ...
  'losscls',{});

I want to specifically know the classes it has like dagnn.Loss(). I tried which dagnn which does not work but help dagnn works. Why does which dagnn not work ? help dagnn works but it does not tell me everything.

>> help dagnn

Contents of dagnn:

dagnn                          - Directed acyclic graph neural network
AffineGridGenerator            - dagnn.AFFINEGRIDGENERATIOR  Generate an affine grid for bilinear resampling
BilinearSampler                - Wrapper for BilinearSampler block:
Crop                           - DagNN cropping layer.
ElementWise                    - DagNN layers that operate at individual spatial locations
Layer                          - Base class for a network layer in a DagNN
Sum                            - DagNN sum layer
UniformScalingGridGenerator    - dagnn.UNIFORMSCALINGGRIDGENERATOR  Generate an iso-tropic scaling + translation

Thanks ! I am aware of that but the website doesn't tell me anything about the function. I want to read the code in dagnn and its members.. And i'd like to know where it is stored. Im not sure why 'which' is not telling me where its stored at

Ok so I just learnt something today. It turns out the classes were 'package folders' so I should read up on it first https://www.mathworks.com/help/matlab/matlab_oop/scoping-classes-with-packages.html
