The attached model contains four common methods for accessing lookup tables within Stateflow. The four examples consist of using a Simulink® block in Stateflow, Embedded MATLAB™ functions in Stateflow, calling a function triggered Simulink subsystem in Stateflow, and including C-code in Stateflow. This is demonstrated in the model interp_1d_examples_r2008b.mdl.
If you are using a version of Stateflow prior to version 7.2 R2008b, you can still call lookup tables using three methods such as using Embedded MATLAB functions in Stateflow, calling a function triggered Simulink subsystem in Stateflow, and including C-code in Stateflow. This is demonstrated in the model interp_1d_examples.mdl.
