If matrix A can be eigendecomposed, and if none of its eigenvalues are zero, then A is invertible and its inverse is given by − = − −, where is the square (N×N) matrix whose i-th column is the eigenvector of , and is the diagonal matrix whose diagonal elements are the corresponding eigenvalues, that is, =.If is symmetric, is guaranteed to be an orthogonal matrix, therefore − = In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, into a collection of smaller matrices Deﬁnition 6.20. En kvadratisk matris kallas inverterbar, om det ﬁnns en kvadratisk matris B av samma ordning s˚a att AB = BA= E. Matrisen B kallas i s˚a fall en invers till A. Inversen till matrisen A betecknas A−1. F¨oljande sats visar att en matris kan ha h ¨ogst en invers. Sats 6.21. Om B och C ¨ar inverser till A,s˚a¨ar B = C

Invertible matrix and its inverse. A square matrix A is called invertible or non-singular if there exists a matrix B such that AB = BA = I n, where I n is the n×n identity matrix with 1s on the main diagonal and 0s elsewhere. If B exists, it is unique and is called the inverse matrix of A, denoted A −1. Definite matri A matrix X is invertible if there exists a matrix Y of the same size such that X Y = Y X = I n, where I n is the n-by-n identity matrix. The matrix Y is called the inverse of X. A matrix that has no inverse is singular. A square matrix is singular only when its determinant is exactly zero Invers betecknar inom matematiken någots motsats eller omvändning . Inverst element - en speciell typ av element i en mängd med avseende på en binär operator på mängden . Multiplikativ invers - talet som ger produkten 1 när det multipliceras med x; Additiv invers - talet, vilket adderat med n, ger noll; Invers funktion - namnet på en funktion som upphäver en annan funktion. In mathematics (specifically linear algebra), the Woodbury matrix identity, named after Max A. Woodbury, says that the inverse of a rank-k correction of some matrix can be computed by doing a rank-k correction to the inverse of the original matrix.
