How to detect change in value in MATLAB?

To detect changes in Stateflow data, use the operators listed in this table. Returns 1 ( true ) if the value of data_name at the beginning of the current time step is different from the value of data_name at the beginning of the previous time step. Otherwise, the operator returns 0 ( false ).

How to detect change in Simulink?

The Detect Change block determines if an input signal does not equal its previous value. The initial condition determines the initial value of the previous input U/z. This block supports only discrete sample times.

What is tick in Stateflow?

temporalCount( tick ) returns the number of times that the chart has woken up since the associated state became active. The implicit event tick is not supported when a Stateflow^® chart in a Simulink^® model has input events. example.
