Converts a linkage matrix generated by MATLAB(TM) to a new
linkage matrix compatible with this module. The conversion does
- the indices are converted from 1..N to 0..(N-1) form,
- a fourth column Z[:,3] is added where Z[i,3] is represents the
number of original observations (leaves) in the non-singleton
This function is useful when loading in linkages from legacy data
files generated by MATLAB.
- Z : ndarray
A linkage matrix generated by MATLAB(TM)
- ZS : ndarray
