Example -- Building an Engine Application on UNIX

MATLAB provides a demonstration program written in the C language that you can use to verify the build process on your computer. The demo file for UNIX systems is called engdemo.c.

Copy the C language MEX-file engdemo.c to your current working directory:

demofile = [matlabroot '/extern/examples/eng_mat/engdemo.c'];
copyfile(demofile, '.');

Build the executable file using the ANSI compiler for Engine stand-alone programs and the options file engopts.sh:

optsfile = [matlabroot '/bin/engopts.sh'];
mex('-f', optsfile, 'engdemo.c');

Verify that the build worked by looking in your current working directory for the file engdemo:

```
dir engdemo
```

To run the demo in the MATLAB Command Window, first make sure your current working directory is set to the one in which you built the executable file, and then type

```
!engdemo
```
