Some matrices behave like numbers that can be divided, as the transformation can be “undone” by multiplication with another matrix. Thus, an invertible matrix is a square matrix that has an inverse matrix, called its inverse. This property is fundamental in solving systems of linear equations, for example, where the inverse allows for a direct computation of the unknown variables of that system.
