About this book

Condensation of Determinants, Being a New and Brief Method for Computing their Arithmetical Values, is by Lewis Carroll. The paper is from the Proceedings of the Royal Society of London and is marked as received on May 15, 1866. The paper says that to solve a set of simultaneous linear equations, not being all homogeneous, by the method of determinants, it is necessary to compute the arithmetical values of one or more determinants.

The paper says the only method hitherto employed, so far as the writer is aware, is that of multiplying each term of the first row or column by the determinant of its complemental minor. The writer proposes a new method of computation, for which Condensation appears to be an appropriate name, and believes it will be found far shorter and simpler than any hitherto employed. The paper uses the word Block for any number of terms arranged in rows and columns.
