How to get the value of each stage in a neural network?

I'm trying to classify using the backpropagation neural network method. My code is successful but I need values from each process/stage such as values from z_inj, z_j, y_ink, y_k, etc. How to get this value? This is my code

net = newff(minmax(feature_tr),[100 1],{'logsig', 'purelin'},'traingdx');
[net_output,tr,Y,E] = train(net,feature_tr,target_tr);
output_ts = round(sim(net_output,feature_ts)); 

I would be very grateful if anyone would help me.

what are z_inj, z_j, y_ink, y_k ?

In neural networks there is a calculation to find a value using the z_inj formula, where in this formula the value of the hidden node will be searched using the weight and bias multiplied by the value of the input layer. My goal in finding the value of each stage is to do manual calculations from neural networks. However, if the calculation is done manually without the help of Matlab, it will take a lot of time because the number of nodes is not small.

weights,bias and many other parameters are present in 'net_output' variable. access these parameters using dot notation. e.g net_output.weights.

im not sure about 'z_inj' values.

OK, thanks for your answer
