When the determinate is zero, the matrix is singular and the inverse matrix does not exist. An “ill-conditioned” matrix has a determinate near zero. In practice, this will mean that computing the inverse will
If an inverse does not exist, the matrix is said to be singular. A nonsingular matrix has a nonzero value for its determinant; a singular matrix has a determinant value equal to zero. Matrices and matrix algebra .Springer USEncyclopedia of Operations Research & Management Science...

This lesson defines the inverse of a matrix and shows how to determine whether a square matrix has an inverse. Includes problems with solutions.
This matrix has no Inverse.Such a matrix is called "Singular", which only happens when the determinant is zero.And it makes sense ... look at the numbers: the second row is just double the first row, and does not add any new information....
TheInverse of a Matrixis thesame ideabut we write itA-1 Why not1/A ? Because we don't divide by a Matrix! And anyway1/8 can also be written8-1 And there are other similarities: When wemultiply a numberby itsreciprocalwe get1 ...

题目In Exercises 35-40, find the inverse of the matrix if it has one, or state that the inverse does not exist.$$ A = \left[ a _ { i j } \right] , a _ { i j } = ( - 1 ) ^ { i + j } , 1 \leq i \leq 4 , 1 \leq j \leq 4 $$ ...
Let’s try one that we know does not have an inverse. Let A = 1 −2 1 −2 . Form the augmented matrix [A| I] = 1 −2 1 0 1 −2 0 1 , and then row reduce it: R 2 = R 2 −R 1 : [A| I] ⇔ 1 −2 1 0 0 0 −1 1 . 3 The zeroes in the botto...
