curve2srvf

Converts a curve to its SRVF representation

Performs alignment, PCA, and modeling of multidimensional and
unidimensional functions using the square-root velocity framework
(Srivastava et al., 2011 <doi:10.48550/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.

curve2srvf function

<dl><dt>beta</dt>
<dd>A numeric matrix of size \(L \times M\) specifying a curve on
an \(L\)-dimensional space observed on an evenly spaced grid of \([0,
 1]\) of length \(M\).</dd>
<dt>is_derivative</dt>
<dd>A boolean value specifying whether the input \(beta\)
is the derivative of the original curve. Defaults to <code>FALSE</code>.</dd></dl>
