regparamrange

Regularization parameter range estimator

Syntax

alphas = regparamrange(K,L)
alphas = regparamrange(K,L,'Property',Value)
Parameters
  • K - Dipolar kernel (NxM-element array)
  • L - Regularization operator ((M-order))xM-element matrix)
Returns
  • alphas - List of regularization parameters (array)

Description

alphas = regparamrange(K,L)

Determines an array of regularization parameters alphas from the generalized singular value decomposition (GSVD) of the dipolar kernel K and regularization operator L.

Additional Settings

Additional settings can be specified via name-value pairs. All property names are case insensitive and the property-value pairs can be passed in any order after the required input arguments have been passed.

alphas = regparamrange(___,'Property1',Value1,'Property2',Value2,___)
  • 'Resolution' - Resolution

    Logarithmic scale resolution of the array of alpha candidates.

    Default: 0.1

    Example:

    alphas = regparamrange(args,'Resolution',0.01)
  • 'NoiseLevel' - Estimation of the noise level

    Estimation of the noise standard deviation of the signal for scaling of the singular values.

    Default: 0

    Example:

    alphas = regparamrange(args,'NoiseLevel',0.05)
