WebbProcrustes analysis, a similarity test for two data sets. Each input matrix is a set of points or vectors (the rows of the matrix). The dimension of the space is the number of columns of each matrix. Given two identically sized matrices, procrustes standardizes both such that: t r ( A A T) = 1. Both sets of points are centered around the origin.

A Procrustean bed is an arbitrary standard to which exact conformity is forced. • In Edgar Allan Poe's influential crime story "The Purloined Letter" (1844), the private detective Dupin uses the metaphor of a Procrustean bed to describe the Parisian police's overly rigid method of looking for clues. • French philosopher Jacques Derrida, in "The Purveyor of Truth", his response to Jacques Lacan's s… Webb24 aug. 2009 · Abstract and Figures.
