Determinant of bidiagonal matrix
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.) WebThe matrix in Example 3.1.8 is called a Vandermonde matrix, and the formula for its determinant can be generalized to the case. If is an matrix, forming means multiplying row of by . Applying property 3 of Theorem 3.1.2, we can take the common factor out of each row and so obtain the following useful result.

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 …
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…
