Line 1: I got interested in higher dimensional deconvolution when contacted by someone about using it as a way of looking for trading indicators in financial time series. I set this task as an example of something that I'm speculating can be done well with functional and array processing languages, but only with difficulty otherwise, which I hope someone will weigh in to confirm or refute. In case anyone wants to know, consistent [[http://~~www~~drop.~~filedropper.com~~io/~~tdat~~yatxacy test data]] were generated partly by this higher dimensional convolution function, <lang Ursala>conv = +^\|(~&x+,DrlDSNiCK9xxSNiCK9K7iFS+ )=>times+ *+ K7\|\x+ iota; * ! plus:-0</lang> invoked as <code>(conv d)(h,f)</code> with dimension <code>d > 0</code> and conforming <code>h</code> and <code>f</code>. (This function essentially subsumes the [[Image convolution]] task as a special case with <code>d = 2</code> and <code>\|h\| = 3</code>.) I suggest a development methodology based on warming up with [[Deconvolution/1D]], then hand coding the solutions for the next few dimensions, and then looking for the pattern.
