How To Plot Transfer Functions In Matlab?

  How can I plot this state space like the graph I attached by using tf() and step() command?

Some CNN architecture are working, other are not

 So i'm using a dataset with 400 images at the moment (looking to add more in the close future), but meanwhile I was trying to find which CNN architectures is the best between the pretrained network from Deep Learning Toolbox.

So i did some test, to compare them with the same parameters, and for exemple, after 10 epoch I have over 95% for validation accuracy for DenseNet, Inceptionv3 or Xception, but I've under 20% for Darknet, VGG, or GoogleNet. Why is there so much of a difference? Is this because my dataset doesn't have enough image? Not enough epochs?

As some of the models are working, but others are not, the issue is likely with the training options used while transfer learning. You might also want to increase the number of samples, especially if the required classes are not well represented in ImageNet dataset. This dataset has been used to train these models, so if the required class are not represented/under represented, then it might be as issue.
Few things to try out are,
  1. Trying to overfit the model on few samples. This suggests that the model is properly set up for training.
  2. If only the validation accuracy is low, then the model is overfitting on the training dataset. Decrease

What are some good alternatives to Simulink?

Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model right in the GUI and with
