Count Events by Using the temporalCount Operator
You can count occurrences of explicit and implicit events by using the
temporalCount operator. For more information, see Temporal Logic Operators.
Collect and Store Input Data in a Vector
This model collects and stores input data in a vector during chart simulation:
The chart contains two states and one MATLAB® function:
Stage 1: Observation of Input Data
The chart awakens and remains in the Observe state, until
the input data u is positive. Then, the transition to the
state Collect_Data occurs.
Stage 2: Storage of Input Data
After the state Collect_Data becomes active, the value of
the input data u is assigned to the first element of the
vector y. While this state is active, each subsequent value
of u is assigned to successive elements of
y using the temporalCount
operator.
Stage 3: Display of Data Stored in the Vector
After 10 ticks, the data collection process ends, and the transition to the
state Observe occurs. Just before the state
Collect_Data becomes inactive, a function call to
status displays the vector data at the MATLAB prompt.
