Dodgson condensation is a method of computing determinants, due to Charles Dodgson (better known as Lewis Carroll). In linear algebra, the determinant is a function that associates a scalar det(A) to every square matrix A. The fundamental geometric meaning of the determinant is as the scale factor for volume when A is regarded as a linear transformation. ...
