Suppose I am using a deep learning model like VGG-16/ResNet/ Inception, The other tools like tensorflow, Keras automatically show the number of parameters used by the candidate network. for example for VGG-Net the number of parameters are 138 Million Also if the network is modified for our own application the number of parameters is important to check the network cost or to make a lighter network. There must be a procedure to check it for DAG network.
Thanks in Advance

I used a function to analyse it manually. I'm not sure if there're better approaches. Here's my code for a dlnetwork object myDLnet (thus the code works for 2019b but not sure for the older version):
function num_para=find_num_para(myDLnet)
num_layers = size(layers,1);
for i=1:num_layers

Hi SC,
While trying your code I'm getiing this error
No appropriate method, property, or field 'Learnables' for class 'SeriesNetwork'.
Error in cnn2>find_num_para (line 160)
