An intuitive utility to help find the CSS path to UI elements on a webpage. These paths are used frequently in a variety of front-end development and QA automation tasks.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

If I now understand you right it is:- what (x,y) values are the same if you convolute linearly or circularly. In which case

You can think of the convolution of A and B as placing the reflection of B on A summing then shifing along/up to calculate the terms 1 by 1. For the 2 techniques to be the same in general you require the shifted matrix no to wrap around the region of have a zero interection with A in this case a 6x6 region.

For a 6X6 region and a pair of 3X4 functions then you when you shift up you have no intersection with A or do not wrap around the top of the region only at y=0,1,2,3. As you move along the x same occurs with the left hand side at x=0,1,2. So the points that would be the same are those in the 4 by 3 block in the corner.

(I have placed the corners of the functions A and B at (0,0) here)

Sorry if I still have problem wrong.
