s= spline(x,y,xq)returns a vector of interpolated valuesscorresponding to the query points inxq. The values ofsare determined by cubic spline interpolation ofxandy. s= spline(x,y,xq)返回与xq中的查询点对应的内插值s的向量。 s的值由x和y的三次样条插值确定。 xq是使用MATLAB画模拟信号图时,坐...
matlab求导代码恒定成熟度三次样条插值 该项目适用于FRE6411固定收益证券课程。 该存储库包含有关英国和美国如何构建其恒定到期收益率曲线的报告,提取收益率曲线数据的R代码以及对数据进行三次样条插值的MATLAB代码。 R代码是从Jerzy Pawlowski教授为金融R课程提供的代码修改而来的。
This step shows how to apply 'natural' cubic spline interpolation to the function f2(x)=((x−2)+)3, and plot the error. The code below computes the 'natural' spline interpolant with an alternative argument syntax that is equivalent to the'variational'argument: using'second'specifies thatcs...
Spline Interpolation of Sine Data Copy Code Copy Command Use spline to interpolate a sine curve over unevenly-spaced sample points. Get x = [0 1 2.5 3.6 5 7 8.1 10]; y = sin(x); xx = 0:.25:10; yy = spline(x,y,xx); plot(x,y,'o',xx,yy) Spline Interpolation with Specifie...
General Spline Interpolation If you want to interpolate at sites other than the breaks and/or by splines other than cubic splines with simpleknots, then you use thespapicommand. In its simplest form, you would saysp = spapi(k,x,y); in which the first argument,k, specifies theorderof ...
