Example: Neuron model

(7.4) |

In this model, the state

Suppose we want to simulate this system for 1000 ms with initial conditions

In addition, a somewhat different appearance is chosen for the Sum block. This block has the option "Icon shape". The default value "round" is used in the previous sections. Now, we use "Rectangular". To add or substract more signals, the option "List of signs" can be changed. For example, adding the first two signals and substracting a third one is achieved by the list of signs "++-".

The neuron model is implemented in Simulink scheme in Figure 7.1:

When simulating this model, the variables

Since this model is *stiff*, the solver type ode15s is used.
