怎么用matlab求complete cubic spline interpolationI need help,I want to construct complete cubic spline interpolations for the data set below.Date:X=[-2.0,-1.5,-1,-0.5,0.0,0.5,1.0,1.5,2.0];Y=[0,0,0,0.87,1,0.87,0,0,0];Graph the data points and the interpolations on a single plot.This is my project.I have no idea to use Matlab to do it.Please help me.Thank you everyone.

(1)the program code
X=[-2。0,-1。5,-1,-0。5,0。0,0。5,1。0,1。5,2。0];
Y=[0,0,0,0。87,1,0。87,0,0,0];
plot(X,Y,'r*')
hold on
Xx=-2。0:0。05:2。0;
Yy=spline(X,Y,Xx);
plot(Xx,Yy,'k')
xlabel('X');ylabel('Y');
legend('The raw data','The interpolation curve')
(2)the figure
