Dodgson condensation Dodgson condensation In mathematics, Dodgson condensation is a method of computing the determinants of square matrices. It is named for its inventor, Charles Lutwidge Dodgson (better known as Lewis Carroll). The method in the case of an "n" × "n" matrix is to construct an ("n" − 1) × ("n" − 1) matrix, an ("n" − 2) × ("n" − 2), and so on, finishing with a 1 × 1 matrix, which has one entry, the determinant of the original matrix. This algorithm can be described in the following four steps: One wishes to find We make a matrix of
Neil Dodgson he worked on image resampling supervised by Neil Wiseman and graduating with a PhD in 1992. Dodgson worked for many years on stereoscopic 3D displays, conducting research principally into autostereoscopic methods. He has contributed to several surveys of the field and has been on the committee of the annual Stereoscopic Displays and Applications conference since 2000, co-chairing the conference four times. With Malcolm Sabin, Dodgson has worked on subdivision surfaces since 2000. Dodgson's team produced the NURBS-compatible subdivision method in 2009. Dodgson has supervised almost twenty research students for PhDs. Dodgson also takes an interest in abstract art. Neil Dodgson
