comment What does it mean to convolve a matrix with a kernel?
Thanks, I assumed that what they meant but I wasn't sure if I was just completely missing it. If I interpret [-1,0,1] as a 2D signal is my pseudo-code correct? One aspect that I'm not sure about is that in a normal convolution operation, you reflect one of the the functions about some line (i.e. the y axis in the 1D case, y=x in the 2D case), but this problem wants to find the "derivatives". Intuitively, I would think this would mean that I shouldn't flip [-1,0,1] around, but if I didn't, then I wouldn't be doing the convolution operation.

I guess part of my confusion has to do with the wording of the problem. It states to convolve the kernel against the horizontal and vertical axes of the matrix.
