Hi, I am trying to plot the following graph :
yi = [3.0 -2.9 4.6 -4.4 4.5]';
ti = [0 1.1 2.2 3.3 4.4]';
plot(ti,yi,'g');
I am getting graph as in figure 1. That is it is triangular wave, but I want sine wave as shown in figure 2.
Can you please help me with it?
Figure 2:
Figure 1:

You have 5 data points and you ve to interpolate the data between them
For plotting in blue cross
plot(ti,yi,'bx','MarkerSize',20,'LineWidth',2)
Now interpolated data and save there result in variable tq and yq
% Your interpolation code
Now plot tq and yq on same graph
hold on
plot(tq,yq,'g--','LineWidth',2)
where tq and yq are your interpolated data
