magni.cs.reconstruction.sl0._mu_start module¶
Module providing functions for calculating the starting value of mu (the relative step-size used in the gradient descent iteration) used in the Smoothed l0 algorithms.
Routine listings¶
- calculate_using_fixed(var)
- Calculate the fixed mu value.
- calculate_using_step(var)
- Calculate an mu value in a ‘step’ way.
- get_function_handle(method)
- Return a function handle to a given calculation method.

wrap_calculate_using_fixed
(var)[source]¶ Arguments wrapper for calculate_using_fixed.

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 mu method.
Returns: f_handle (function) – Handle to the calculation method defined in this globals scope.
