hi i would like to get an interpolation formula using: spline, pchip and makima for example:
clc;clear;close all
x=[1 2 3 4 5];
v=[0 1 0 1 0];
tt=linspace(1,5);
xq=1.5;
vq1=interp1(x,v,tt,'spline');
plot(x,v,'o',tt,vq1,'r')
legend('puntos','spline','location','southeast')

You can look into the interp1 function for 1-D data interpolation. You can go through various Interpolation methods to know more about implementing methods like spline, pchip and makima.
