Dodgson's method of determinants
WebThe nineteenth-century mathematician Charles Dodgson is best known by the name Lewis Carroll, the pseudonym under which he wrote the Alice books. However, he also wrote a treatise on the theory of determinants (Dodgson 1867), and worked on a method for calculating these, which is sometimes referred to as Dodgson condensation. WebCondensation, developed by Charles Dodgson, is an uncommon method for calculating the determinant. It is generally considered to be numerically unstable due to its itera-tive …

Webthat the symbolic method seems more simple, since it does not need new sub-matrices or determinant calculates. Specially, it preserves the general simplicity and the idea of Dodgson’s method. However, the above method does not yield the correct result in some cases if we replace the zero entries in the interior of intermediate matrix A(n k) with WebAbstract. Here we examine Dodgson's Method, a fraction-free methods for computing determinants. In some cases, this method fails due to division by zero. eW propose a …

Web1 The Method of Condensation The idea originated with Charles L. Dodgson and the iterative form is propelled by Zeilberger [7]. Here are some instances of its application. 1.1 Example. Consider the n × n matrix of entries 2i j. Let us compute the determinant. The first step is to generalize it (introduce two additional parameters) as Zn(a,b ... WebThe method is sometimes referred to as Dodgson’s Condensation Method, or condensation, because with each iteration a matrix is replaced by a smaller one until a 1 …
