Web15 jan. 2024 · In linear algebra, an n-by-n square matrix A is called Invertible, if there exists an n-by-n square matrix B such that where ‘In‘ denotes the n-by-n identity matrix. The matrix B is called the inverse … WebThe determinant of the matrix must not be zero (determinants are covered in section 6.4). This is instead of the real number not being zero to have an inverse, the determinant must not be zero to have an inverse. A square matrix that has an inverse is called invertible or non-singular. A matrix that does not have an inverse is called singular.
