exp_zero_seq

odl.solvers.iterative.iterative.exp_zero_seq(base)

Default exponential zero sequence.

It is defined by

t_0 = 1.0 t_m = t_(m-1) / base

or, in closed form

t_m = base^(-m-1)

Parameters

basefloat

Base of the sequence. Its absolute value must be larger than 1.

Yields

valfloat

The next value in the exponential sequence.
