This one-day course presents multiple methods for integrating C code into Simulink® models. Topics discussed include the C Caller and C Function blocks, Legacy Code Tool for wrapping external C functions into Simulink, and manually written C MEX S-functions. This course is intended for intermediate to advanced Simulink users.
