magni.cs.reconstruction.it._step_size module¶
Module providing functions for calculating the step-size (relaxation parameter) used in the Iterative Thresholding algorithms.
Routine listings¶
- calculate_using_adaptive(var)
- Calculate a step-size value in an ‘adaptive’ way.
- calculate_using_fixed(var)
- Calculate the fixed step-size value.
- get_function_handle(method)
- Return a function handle to a given calculation method.

get_function_handle
(method, var)[source]¶ Return a function handle to a given calculation method.
Parameters: - method (str) – Identifier of the calculation method to return a handle to.
- var (dict) – Local variables needed in the step-size method.
Returns: f_handle (function) – Handle to calculation method defined in this globals scope.
