TrueTime 1.13b READMETrueTime is Matlab-based and requires Matlab 6.5 (R13) with Simulink5.0 or Matlab 6.1 (R12.1) with Simulink 4.1. The simulator softwareconsists of a Simulink block library and a collection of C++ functionswith corresponding Matlab MEX interfaces.INSTALLATION   1. Extract the files to some suitable directory $DIR   2. Set the environment variable TTKERNEL to $DIR/kernel   3. Start Matlab   4. Add $DIR/kernel and $DIR/kernel/matlab to the Matlab path   5. The block library is opened using      >> truetime   6. See the README-files in the examples directories for      instructions on how to compile and run the provided examplesCOMPILATION OF MEX FILESThe TrueTime MEX files can be compiled using the command ttmex. Thiscommand simply adds the argument -I$DIR/kernel to the mex command.You must make sure that your Matlab mex command is functioningproperly with C++ files. The simulator works with (at least) thefollowing compilers:    * Microsoft Visual Studio C++ 6.0 under Windows    * GNU gcc 2.96 under Linux and Solaris To select a compiler, run mex -setup in Matlab.
