It is shown that certain rank-one and rank-two corrections to symmetric positive definite matrices may be expressed in the form of a product. This product form gives control over the positive definiteness, determinant value and condition... KW Brodlie,AR Gourlay,J Greenstadt - 《J.inst.math...
MATRICES (Mathematics)MATHEMATICSCOMBINATORICSALGEBRAWe investigate the complexity of enumerative approximation of two fundamental problems in linear algebra, computing the rank and the determinant of a matrix. We show that both are as hard to approximate (in the enumerative sense) as...
In this case, the matrix is non-singular (has an inverse), and its determinant is non-zero. Rank-Deficient Matrix: If the row rank and column rank are less than the smaller of the two dimensions, the matrix is said to be rank-deficient. Rank-deficient matrices have linearly dependent ...
The concept of matrix rank is related to two topics that have already been discussed in earlier chapters: 1. linear dependence of a set of row or column vectors, 2. the determinant of a matrix.There are two basic, and compatible, ways of defining the rank of a matrix. One definition ta...
