Gradient_cpp

<p>is a data vector. Its first K*n components are cluster centroids and its last K components are the centroid weights.</p>

<p>Global objective function and gradient computations with respect to cluster centroid vectors and their weights.</p>

Routines for efficient cluster analysis of large scale data. This package implements the 'CHICKN'
clustering algorithm (see 'Permiakova' 'et' 'al.' (2020) "'CHICKN': Extraction of 'peptide' 'chromatographic'
'elution' profiles from large scale mass 'spectrometry' data by means of 'Wasserstein' 'compressive' hierarchical
cluster analysis"). Functions for data compression, hierarchical clustering and post processing are provided.
