Detailed Description

Measures the convergence from an old data set to a new one.

The convergence is evaluated by looking at the two norm of the differences between each data value from the new and old data set. If the two norm is equal or below a given percentage of the norm of the old data set, convergence is achieved.

For a description of how to perform the measurement, see class ConvergenceMeasure.
