1.Something that is opposite, as in sequence or character; the reverse. 2.MathematicsOne of a pair of elements in a set whose result under the operation of the set is the identity element, especially: a.The reciprocal of a designated quantity. Also calledmultiplicative inverse. ...
IfAissymmetricacross its main diagonal. ThenA−1is also symmetric. IfAistridiagonal(only three nonzero diagonals),A−1is a dense matrix with no zeros. This is another reason why we don't often compute inverse matrices. The inverse of a band matrix is generally a dense matrix. ...
the inverse of a matrix
1 Definition of the Inverse Inverses are defined only for square matrices. Thus, we start with an n×n (square) matrix A. We say that an n × n matrix B is an inverse for A if and only if AB = BA = I, where I is the n ×n identity matrix. The reason that we want ...
