#算法的核心就是利用scipy中的interpolate来完成工作
#一共是5种一维插值算法形式:
#插值方法#xff1a;1.阶梯插值 2.线性插值 3.2阶样条插值 4.3阶样条插值
#nearest阶梯插值
#zero1.阶梯插值 2.线性插值 3.2阶样条插值 4.3阶样条插值
#nearest阶梯插值
#zero阶梯插值
#slinear线性插值
#quadratic2阶样条插值
#cubic3阶样条插值
#最后写成列表形式:style[nearest,zero,slinear,quadratic,cubic] 2.算法核心代码
#导入库和数据
import numpy as np
from scipy import interpolate
import pylab as plbx0np.linspace(0,10,11)
