Generate samples from the Generalized Stoner-Wohlfarth Astroid

flatspin.astroid.db

Astroid database table.

Type:

pd.DataFrame

flatspin.astroid.astroid_params(**filter)

Lookup parameters from the astroid database.

Parameters:

**filter (dict) – column=value to match one row from the database. Consult astroid.db.columns for available column names.

Examples

>>> astroid_params(shape="stadium", width=220, height=80, thickness=20)
