Integrating MATLAB with C Code register

 

Course Highlights

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

Course Objectives

The aim of this course is to provide participants on interfacing user-written C code with Matlab

Who Must Attend

This hands-on course is designed for engineers who wish to interface their Matlab code with user-written C code

Course Benefits

Upon the completion of the course, the participants 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, and identify the proper approach for interfacing Matlab with C code

Prerequisites

Familiarity with terminology and concepts related to programming in C (especially pointers). Experience with Matlab is recommended
