Details on the file_formats module¶

For a description on how to use the most important functionality, please checkout the tutorials and the API documentation.

The following example code shows how to use most of the functionality of the tempo.file_formats module. This code is suplementary to the documentation and also includes functionality that is only relevant to the inner workings of the TimeEvolvingMPO package. Sections that show example code that is not part of the API is marked with three asterix ***.
