三次样条插值
• yi = interp1(x,Y,xi,method) returns vector yi containing elements corresponding to the elements of xi and determined by interpolation within vectors x and Y. The vector x specifies the points at which the data Y is given. -'nearest'--Nearest neighbor interpolation -'linear‘--Linear interpolation -'spline‘--Cubic spline interpolation -'pchip‘--Piecewise cubic Hermite interpolation
