In this column and its successor, we describe and explain some algorithms and data transforms beyond those commonly used. We present and discuss algorithms that are rarely, if ever, used in practice, despite having been described in the literature. These comprise algorithms used in conjunction with continuous spectra, as well as those used with discrete spectra.
