I want only the minimum points in the blue plot. I want an almost parabolic curve open downwards. ' islocalmin ' and , 'envelope' functions are not woking. How could I acheive it?
the orange plot is it's Savitzky–Golay filter output.

Attach data or code to create some.

Well, if 'not working' is as much information as you want to give I guess the question is at an end?!

And the code you are running is what?!

The movmin function might work for you. If you want us to help with the tweaking, you will have to attach your data or some code that can generate plausible data.

You didn't provide any method of using your raw data to get the plot, nor the code you tried. This way it is very difficult to help you.
