Padded with 0's in convolution kernel to avoid collisions
Wow, using a string really cuts down on solution size.
Can someone please tell me whats going on?!
The reshape function creates a matrix with the vector [1 3 9 27] placed vertically, horizontally, and diagonally; the conv2 function does sort of a dot product of these with all sets of four elements in the test matrix; if [1 1 1 1] or [2 2 2 2] appears, the result will be 40 or 80, respectively.
