Use vectors and matrices when you want to:
Process multidimensional input and output signals
Combine separate scalar data into one signal
For more information, see Examples of Vectors and Matrices in Stateflow Charts.
You can define vectors and matrices at these levels of the Stateflow hierarchy:
Charts
Subcharts
States
Functions
You can use vectors and matrices to define:
Input data
Output data
Local data
Function inputs
Function outputs
You can also use vectors and matrices as arguments for:
State actions
Transition actions
MATLAB functions (see Using MATLAB Functions in Stateflow Charts)
Truth table functions (see Truth Table Functions for Decision-Making Logic)
Graphical functions (see Graphical Functions for Reusing Logic Patterns and Iterative Loops)
Simulink functions (see Using Simulink Functions in Stateflow Charts)
Change detection operators
For more information, see Operations That Work with Vectors and Matrices in Stateflow Action Language and Rules for Using Vectors and Matrices in Stateflow Charts.
