This one-day course presents multiple methods for integrating code into Simulink models. The focus will be on integrating C and MATLAB®. Topics discussed will include M-file and C-MEX S-functions, Embedded MATLAB, and the Legacy Code Tool for wrapping external C functions into Simulink. This course is intended for intermediate to advanced Simulink users.
Pre-requisites
"Simulink for System and Algorithm Modeling", "MATLAB Fundamental and Programming Techniques", and knowledge of C programming.
