I need help with solving the task in Simulink + Stateflow

Hello everyone. I have this task, does anyone have any ideas on how to do this or ready-made examples of something like this?

Need to make the model of specified below system and make software test.

System description

Input:

- only one input

- during all time input gets a series of data

- at each cycle input signal is either 0 or 1

- type boolean

Output:

- only one output

- at each cycle time, the system sets the output 0 or 1 that depends on

conditions

- the system sets the output to 1 if the sum of 1 in the last input

series was odd.

- in other cases, the system sets the output to 0

- type boolean

Definition of the series:

Series starts with 2 nd 1 in sequence (1 | 1).

Series ends after 2 nd 0 in sequence (0 0 |).

Example of input data and series:

input 0 1 0 1 | 1 1 1 0 0 |1 0 0 1| 1 1 1 0 1 0 0| 0 0

output 0 0 0 0 | 0 0 0 0 1 |1 1 1 1| 1 1 1 1 1 1 0| 0 0

Requirements to the software models:

* should be done in simulink and stateflow

* test example above should be included as test case

Hi Paul,

Processing the input data can be performed with two different states for series and non-series boolean values, using a Stateflow chart. These states can be used to evaluate the data and produce the desired output.

The following steps can be undertaken to achieve the task:

1. Add a Chart: Begin by adding a ‘chart’ to your Simulink workspace. This chart will contain the states and logic necessary for processing the input.
2. Input Data: Use a ‘From Workspace’ block to pass the input data to this chart. The data can be defined in the base workspace.
3. Define States: Inside the chart, create two states to represent the series and non-series data. Utilize variables to store the last and the second-to-last inputs.
4. State Transitions: Implement transitions to switch between the states based on the series definition.
5. Series State Logic: Within the series state, introduce a counter variable to tally the number of 1’s.
6. Output Update: Upon entering the non-series state, check whether the counter is even or odd and update the output accordingly.

I've attached an image of an example implementation I tried, which might be helpful.

Also, the Stateflow Onramp is a great resource to get started with Stateflow. Kindly refer to the following link for the same: https://matlabacademy.mathworks.com/details/stateflow-onramp/stateflow
