Web15 mei 2024 · The inverse of a matrix is an important operation that is applicable only to square matrices. Geometrically the inverse of a matrix is useful because it allows us to compute the reverse of a transformation, i.e. a transformation that undoes another transformation. There are several ways to calculate the inverse of a matrix.
