I have a set of data that I have used to plot the graph below. I am needing to find the area of the shaded area but cannot work out how to as I do not know what range of values make up this section and, as the data loops round multiple times there will be a few sets. The data used was two 2000x1 double vectors. Any help would be appreciated.
Note: The shading was done in photoshop as I do not know how to do this in Matlab earlier.
