This is a recursive function takes any of the following data objects commonly associated with data logging in Simulink:
  Simulink.ModelDataLogs
  Simulink.SubsysDataLogs
  Simulink.ScopeDataLogs
  Simulink.TsArray
  Simulink Timeseries

This function outputs an nxm matrix of type double where:
  n = length of the timeseries data
  m = number of timeseries in the input (if the input is a
      Timeseries, m = 1).

output_matrix = CreateMatrixFromModelData(inputTsArray)

This function is particularly useful in conjunction with bus signals, signal logging, and the Limit Check element in SystemTest. When signal logging is enabled for a bus signal in Simulink, the data is saved as a Simulink.TsArray. As of R2009b, the Limit Check Element in SystemTest only supports native Simulink data types. The matrix output of this function is fully compatible with the Limit Check element. As such, this provides a quick way to compare bus signals in the limit check element.

This function works well along with the functions in the acknowledgments section.
