6.4 The NewAMatrix Class

The NewAMatrix class provides an instance of a numerator relationship matrix as a NumPy array of floats with some convenience methods. The idea here is to provide a wrapper around a NRM so that it is easier to work with. For large pedigrees it can take a long time to compute the elements of A, so there is real value in providing an easy way to save and retrieve a NRM once it has been formed.
