MLEX: Interfacing MATLAB with C Code

This one-day course focuses on interfacing MATLAB® with user-written C code. Through hands-on examples and exercises, the course explores generating MEX-files to incorporate external C code in MATLAB applications and calling MATLAB code from C applications. At the end of this course, attendees will be able to:

Write and compile source MEX files
Pass data between MATLAB and MEX files
Call MATLAB code from C code using the engine interface
Identify the proper approach for interfacing MATLAB with C code.
