Would that not just be the inverse matrix? http://mathworld.wolfram.com/MatrixInverse.html http://mathworld.wolfram.com/MatrixInverse.html

  Nope, and in general it doesn't exist. That said, there are techniques for "deconvolution" which partially reverse (or in some, special cases completely reverse) a kernel convolution.

    Ah, thanks. I guess that makes sense since this isn't straightforward matrix multiplication.

      I would suggest to try a 1-dimensional example first. In that case, the kernel does not look like a matrix, but more like a vector.
