ubermagutil.hysteresis_values

ubermagutil.hysteresis_values(vmin, vmax, step)

Generate hysteresis values.

Given vmin, vmax, and step, hysteresis loop values are generated and list is returned. The first and the last values in the result are vmax.

If vmax - vmin range cannot be divided into integer number of steps, ValueError is raised.

Parameters:

• vmin (numbers.Real) – Minimum value

• vmax (numbers.Real) – Maximum value

• step (numbers.Real) – Step value

Returns:

Hysteresis values.

Return type:

list

Raises:

ValueError – If vmax - vmin range cannot be divided into integer number of steps.

Examples

1. Generate hysteresis values.

>>> import ubermagutil as uu
...
>>> uu.hysteresis_values(-1, 1, 1)
[1.0, 0.0, -1.0, 0.0, 1.0]
