Example -- Building an Engine Application on Windows

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 Windows systems is engwindemo.c.

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

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

Look in the \bin\win32\mexopts directory for the appropriate options file for the Lcc compiler. Use the commands shown here to build the executable file using this compiler:

optsfile = [matlabroot '\bin\win32\mexopts\lccengmatopts.bat'];
mex('-f', optsfile, 'engwindemo.c');

Verify that the build worked by looking in your current working directory for the file engwindemo.exe:

```
dir engwindemo.exe
```

To run the demo from 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

```
!engwindemo
```
