WEBDec 4, 2018 · The inverse of a matrix is like the reciprocal of a number. The inverse of an n\times n matrix A is A^ {-1} ,an n\times n matrix, such that A⋅A^ {-1}=I, where I is the identity matrix. Just like how the product of a number and its reciprocal equals 1, ( \frac {1} {n}⋅n=1 ), the product of a matrix and its inverse equals the identity matrix.
