Basically I have two vectors ( a 1,..., a n) and ( b 1,..., b n − 1) that form the "reverse" diagonals of a matrix A. So that A 1, n = a 1,..., A n, 1 = a n and A 1, n − 1 = b 1,..., A n − 1, 1 = b n − 1 and all other A i, j = 0.

If the diagonal is a 1, a 2, …, above diagonal b 1, b 2, … and below diagonal is c 1, c 2, …, then the determinant of the n -th principal minor (i.e. the matrix formed by the top left n × n submatrix) is given by the following recursion: f 1 = a 1 , f 0 = 1, f − 1 = 0
WebDec 30, 2015 · A non-sparse n x n matrix has a determinant involving n! terms of length n so unless there are entries that are 0, the memory requirements would be in excess of n * (n!) . If your matrix is not marked as sparse then all n! of those calculations might actually be done (though the position of the 0s might matter in the efficiency.) WebThis video provides an example of how to calculate the determinant using the diagonal method.Site: http://mathispower4u.com
In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism. The determinant of a product of matrices is the product of their determinants (the preceding property is a corollary of this one). The determinan…

The determinant is a special scalar-valued function defined on the set of square matrices. Although it still has a place in many areas of mathematics and physics, our primary application of determinants is to define eigenvalues and characteristic polynomials for a square matrix A.It is usually denoted as det(A), det A, or A .The term determinant … only walkWebOct 24, 2016 · There is also another commonly used method, that involves the adjoint of a matrix and the determinant to compute the inverse as inverse(M) = adjoint(M)/determinant(M).
