== higher dimensional deconvolution ==
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://drop.io/yatxacy test data]] were generated partly by this higher dimensional convolution function,
<lang Ursala>conv = +^|(~&x+,*DrlDSNiCK9xxSNiCK9K7iFS+ *)=>times+ **+ *K7|\x+ iota; * ! plus:-0</lang>

I am new here, but I think the definition of convolution is wrong and should be
:<math>G(n_0, \dots, n_{d-1})=\sum_{m_0=-\infty}^{\infty}\dots\sum_{m_{d-1}=-\infty}^{\infty}F(m_0, \dots, m_{d-1})H(n_0-m_0, \dots, n_{d-1}-m_{d-1})</math>
in accordance with [[http://en.wikipedia.org/wiki/Convolution#Definition|Wiki convolution]]

My bad. It's fixed now.
