    <p>Basis functions are created with
<code>fda::create.bspline.basis(domain, n_basis)</code>, i.e.
B-spline basis functions of order 4 with equally spaced knots
are used to create <code>mfd</code> objects.</p>
<p>The smoothing penalty lambda is provided as
<code>fda::fdPar(bs, 2, lambda)</code>,
where bs is the basis object and 2 indicates
that the integrated squared second derivative is penalized.</p>
