Dear All,
From time analysis I get some values. Ideally my curve should monotonically increase. But due to some noice my curve get little zigzag. How Can I make my curve smooth. To understand please execute the following Code.
x = [1:100];
noice = [5:5:100];
x(noice) = x(noice) - 1;
plot(x);
How can I make my curve smooth.

Hi, one thing you can do is use a moving average filter:
y = filter(1/5*ones(5,1),1,x);
plot(y);
