Parameters ========== Background ----------- Parameter is a type of building atom for DAE models. Most parameters are read directly from an input file and passed to equation, and other parameters can be calculated from existing parameters. The base class for parameters in ANDES is `BaseParam`, which defines interfaces for adding values and checking the number of values. `BaseParam` has its values stored in a plain list, the member attribute `v`. Subclasses such as `NumParam` stores values using a NumPy ndarray. An overview of supported parameters is given below. .. currentmodule:: andes.core.param .. autosummary:: :recursive: :toctree: _generated BaseParam DataParam IdxParam NumParam ExtParam TimerParam
