DNAOAD (Dual Number Arbitrary Order Automatic Differentiation) is a Fortran implementation of dual numbers for arbitrary order automatic differentiation.

🧪 Running Examples

To run the examples, navigate to the examples directory and use a terminal. For example:

sh create_exec.sh ex1.f90

On Windows, use:

create_exec.bat ex1.f90

Note: Alternatively (and this is the recommended method), you can manually compile and run the source files.

⚙️ Manual Compilation

The examples in the SourcesF folder can be compiled directly using the Intel Fortran compiler:

ifx ex3.f90

If you're using gfortran, use the SourcesF_gfortran folder instead.
