Summary

Perform a natural logarithm of a MDHistoWorkspace.

Properties

Name Direction Type Default Description
InputWorkspace Input IMDWorkspace Mandatory A MDEventWorkspace or MDHistoWorkspace on which to apply the operation.
OutputWorkspace Output IMDWorkspace Mandatory Name of the output MDEventWorkspace or MDHistoWorkspace.
Filler Input number 0 Some values in a workspace can normally be zeros or may get negative values after transformations log(x) is not defined for such values, so here is the value, that will be placed as the result of log(x<=0) operation Default value is 0
Natural Input boolean True Switch to choose between natural or base 10 logarithm. Default true (natural).

Description

This executes the natural logarithm operation on a MDHistoWorkspace.

The signal a becomes f = log(a)

The error da becomes df^2 = a^2 / da^2

This algorithm cannot be run on a MDEventWorkspace. Its equivalent on a MatrixWorkspace is called Logarithm v1.
