The MATLAB Compiler Suite: M-Files to C/C++ Executable Programs

Ray Bachnak Roger Lee Texas A&M University-Corpus Christi Naval Air Systems Command

Abstract

MATLAB has been recognized as the premier program for numerical computations and data visualization. Due to the fact that MATLAB is an interpreted language, M-files execute slower than compiled programs written in other languages. Furthermore, M- files require the presence of MATLAB to run. Recently, The MathWorks introduced a set of tools to automatically convert M-files into C/C++ source code, which can then be compiled to produce stand-alone executable code. This paper discusses the features of the Compiler, describes the conversion process, and presents test results that compare execution times of M-files and C/C++ executable applications.

Introduction

MATLAB is a powerful language that simplifies the process of solving technical problems in a variety of disciplines by including a very extensive library of predefined functions. It also offers many special-purpose toolboxes that address specific areas, such as signal processing and neural networks, and provides Graphical User Interface (GUI) tools that make it suitable for application development. Because of these capabilities, MATLAB has been recognized as the premier program for numerical computations and data visualization and has been used by the educational, industrial, and government communities all over the world.

Due to the fact that MATLAB is an interpreted language, MATLAB files (M-files) execute slower than compiled programs written in other languages, such as C, C++, and Fortran. In addition, M-files require the presence of MATLAB to run. To address these weaknesses, The MathWorks recently introduced a set of tools that automatically convert M-files into C/C++ source code, which can then be compiled to produce C/C++ executable programs that can run even if MATLAB is not installed on the system. These C/C++ executable programs are referred to as stand-alone applications. The tools required for generating stand-alone applications are: MATLAB, the MATLAB Compiler, the MATLAB C/C++ Math Library, and a C/C++ compiler. The MATLAB C/C++ Graphics Library is also required in order to create applications that make use of Handle Graphics ® functions. This paper describes the important features of the Compiler and its associated tools, states the benefits of converting M-files to stand-alone
