Inverse of a Matrix - Math is Fun
First of all, to have an inverse the matrix must be "square" (same number of rows and columns). But also the determinant cannot be zero (or we end up dividing by zero). How about this:

The inverse of Matrix for a matrix A is A^-1. The inverse of a matrix can be found using a simple formula (adj A) / |A|. Learn about the matrix inverse formula for the square matrix of order 2 × 2 and 3 × 3 using solved examples.
Matrix Inverse -- from Wolfram MathWorld
2024年12月31日 · The inverse of a square matrix A, sometimes called a reciprocal matrix, is a matrix A^(-1) such that AA^(-1)=I, (1) where I is the identity matrix. Courant and Hilbert (1989, p. 10) use the notation A^_ to denote the inverse matrix.
3.5: Matrix Inverses - Mathematics LibreTexts
2022年9月17日 · Understand what it means for a square matrix to be invertible. Learn about invertible transformations, and understand the relationship between invertible matrices and invertible transformations. Recipes: compute the inverse matrix, solve a linear system by taking inverses. Picture: the inverse of a transformation.
It is therefore natural to denote the matrix B in (2.6.1) by A−1 and to call it the inverse of A. The following definition introduces the appropriate terminology. Let A be an n n matrix. If there exists an n n matrix A−1 × × satisfying. then we call A−1 the matrix inverse to A, or just the inverse of A. We say that A is invertible if A−1 exists.

There are two ways to determine whether the inverse of a square matrix exists. Determine its rank. The rank of a matrix is a unique number associated with a square matrix. If the rank of an n x n matrix is less than n, the matrix does not have an inverse. We showed how to determine matrix rank previously. Compute its determinant.
