4 Calling MATLAB from C and Fortran Programs

4-6

Examples of Calling Engine Functions

This section contains examples that illustrate how to call engine functions from

C and Fortran programs. The examples cover the following topics:

•“Calling MATLAB From a C Application”

•“Calling MATLAB From a Fortran Application”

•“Attaching to an Existing MATLAB Session”

It is important to understand the sequence of steps you must follow when using

the engine functions. For example, before using

engPutArray, you must create

the matrix, assign a name to it, and populate it.

After reviewing these examples, follow the instructions in “Compiling and

Linking Engine Programs” on page 4-17 to build the application and test it. By

building and running the application, you will ensure that your system is

properly configured for engine applications.

Calling MATLAB From a C Application

This program, engdemo.c, illustrates how to call the engine functions from a

stand-alone C program. For the Windows version of this program, see

engwindemo.c in the <matlab>\extern\examples\eng_mat directory. Engine

examples, like the MAT-file examples, are located in the

eng_mat directory.
