I am doing a VEE coding that to extract out the 2 difference size array data and make some calculation on it. Example, array 1 got 10 freq points with 10 data, array 2 got 3 freq points with 3 data. The 3 freq points in array 2 are included in array 1, so how can i extract them out, and compare them and subtract the desired value of particulars points within both arrays? Can anyone please kindly advice?? Thanks!

I have attached the examples of both difference size array.
