From the developer:
Multidimensional Scaling refers to a family of models where the structure in a set of data is represented graphically by the relationships between a set of points in a space. MDS can be used on a variety of data, using different models and allowing different assumptions about the level of measurement.
You may want to check out more software, such as SSSort, Quick Timer High or Torque on an Electric Dipole in a Constant Field, which might be similar to NewMDSX.
