PlasmaCalcs.tools.array_select.select_i_closest

PlasmaCalcs.tools.array_select.select_i_closest(listlike, x, force_relative=None)

returns the index of the value closest to x. If x iterable, [select_i_closest(y) for y in x]

raise ValueError if that is impossible (e.g. if force_relative=’equal’ and no value == x).

force_relative: None, ‘before’, ‘after’, ‘equal’, or ‘isclose’

whether to also force a certain relationship between result and x:

result <= x (if ‘before),

result >= x (if ‘after’),

result == x (if ‘equal’),

np.isclose(result, x, atol=0) (if ‘isclose’).
