body: <p>Hi everybody I have a simple matrix like this Ex = [ 1 5; 2 5; 4 15; 5 15; 7 25; 8 25]; and it is graph is like below. I want to keep the same shape of the signal with more samples. In other words I need to have more rows in my matrix with corresponding values in between, keeping the same behaviour.
