open-in-new
<p>In the <a href="/facts/Mathematics/pxTouaz4">mathematical</a> field of <a href="/facts/Numerical_analysis/QT9cYa9z">numerical analysis</a>, monotone cubic interpolation is a variant of <a href="/facts/Cubic_interpolation/S29nwRUF">cubic interpolation</a> that preserves <a href="/facts/Monotone_function/MjQK0YL2">monotonicity</a> of the <a href="/facts/Data_set/eDvegUTK">data set</a> being interpolated. </p><p>Monotonicity is preserved by <a href="/facts/Linear_interpolation/galkvRGy">linear interpolation</a> but not guaranteed by <a href="/facts/Cubic_interpolation/S29nwRUF">cubic interpolation</a>. </p>
