class History(change_points, vals)

Bases: object

Base class piecewise constant history. The first epoch starts at zero, and the last epoch extends to infinity.

Parameters

• change_points (array) – epoch change points (times)

• vals (ndarray) – constant values for each epoch (rows)

Methods

arrays	Return time grid and values in each cell.
check_grid	Test if time grid is the same as another instance.
epochs	Generator yielding epochs as tuples: (start_time, end_time, value)
plot	Plot the history.

arrays()

Return time grid and values in each cell.

epochs()

Generator yielding epochs as tuples: (start_time, end_time, value)

check_grid(other)

Test if time grid is the same as another instance.

Parameters

other (History) – another History object

plot(t_gen=None, types=None, **kwargs)

Plot the history.

Parameters

• t_gen (Optional[float]) – generation time in years (optional)

• kwargs – key word arguments passed to plt.plot

Return type

List[Line2D]
