Matrix Inverse Matrix Inverse The inverse of a square matrix , sometimes called a reciprocal matrix, is a matrix such that (1) where is the identity matrix. Courant and Hilbert (1989, p. 10) use the notation to denote the inverse matrix. A square matrix has an inverse iff the determinant (Lipschutz 1991, p. 45). A matrix possessing an inverse is called nonsingular, or invertible. The matrix inverse of a square.. 더보기 이전 1 ··· 573 574 575 576 577 578 579 ··· 610 다음
