How can I write a script that plots the data and then interpolates it with a smooth curve (plot
the curve too). also find and plot the value of y for t=4.
t 0 0.5 1.0 6.0 7.0 9.0
y 0 1.6 2.0 2.0 1.5 0

t = [0 0.5 1.0 6.0 7.0 9.0];
y = [0 1.6 2.0 2.0 1.5 0];
y_when_t_is_4 = interp1(t,y,4);
xx=linspace(t(1),t(end),1000);
yy=interp1(t,y,xx,'spline'); % use whatever method suits you the best
plot(t,y,'o',xx,yy)
