[Ans] spline [Description] spline is abbrevaition of sample point linearly interpolation. (I guess.) (1) s = spline( x , y , xq ) ; It will return a vector of interpolated values s corresponding to the query points in xq . The values of s are determined by cubic spline interpolation of x and y . (2) pp = spline(x,y) ; It will return a piecewise polynomial structure for use by ppval and the spline utility unmkpp . more details on: Cubic spline data interpolation - MATLAB spline (mathworks.com) code clear clc help spline ; %spline example1 %fig(a) 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 example2 %fig(b) x = -4:4; y = [0 .15 1.12 2.36 2.36 1.46 .49 .06 0]; cs = spline...
