Return Value

A system of simultaneous linear equations has a unique solution if its determinant is not equal to zero.

Determinants are only defined for square matrices. If the matrix is not square, an exception of type DimensionMismatchException is thrown.

For a QR factorized matrix A = QR, the magnitude of the determinant is the product of the diagonal elements of R. Since Q is orthogonal, its determinant is 1 or -1.
