4x4 Matrix Inverse calculator to find the inverse of a 4x4 matrix input values. The matrix has four rows and columns. It is a matrix when multiplied by the original matrix yields the identity matrix. The inverse of a square n x n matrix A, is another n x n matrix, denoted as A-1. So the 'n x n' identity matrix is written as A A-1 = A-1 A = I. Not all matrices have an inverse, but if a matrix has inverse then it is called as Invertible or Nonsingular Matrix.
Not all the 4x4 matrix are the Invertible matrix. If the Matrix's determinant is equal to zero, then it is an invertible matrix (inverse matrix).
