curve_srvf_align

Aligns a collection of curves using the elastic square-root velocity (srvf) framework.

srvf

Performs alignment, PCA, and modeling of multidimensional and
unidimensional functions using the square-root velocity framework
(Srivastava et al., 2011 <arXiv:1103.3817> and
Tucker et al., 2014 <DOI:10.1016/j.csda.2012.12.001>). This framework
allows for elastic analysis of functional data through phase and
amplitude separation.
