摘要
介绍了三次样条插值的基本概念及运用Matlab求三次样条插值的方法,并将该方法应用到氢原子光谱实验中,应用直线拟合方法求出了氢原子光谱的波长.
The basic methods of cubic spline interpolation are introduced and the Matlab programs for cubic spline interpolation are given. When this method is applied to the hydrogen atom spectroscopy experiments, the wavelengths of the hydrogen atom spectrum can be easily obtained. Finally linear fitting method is described succinctly.
