Signature

def   helmert ( n ,  full = False )

Summary

Create an Helmert matrix of order n.

Extended Summary

This has applications in statistics, compositional or simplicial analysis, and in Aitchison geometry.

Parameters

n : int

The size of the array to create.

full : bool, optional

If True the (n, n) ndarray will be returned. Otherwise the submatrix that does not include the first row will be returned. Default: False.

Returns

M : ndarray
