I have an array x and an array y. From these two arays I ploted the curve on the picture belove. The question is how to find the area inside of the curve. I used polyarea(x,y), but I am not sure that it is correct. I will be grateful for any opinion. Thank you!![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/730659/image.png)
