WebThe inverse of a 3x3 matrix A is calculated using the formula A-1 = (adj A)/(det A), where. adj A = The adjoint matrix of A; det A = determinant of A; det A is in the denominator in the formula of A-1.Thus, for A-1 to exist det A should not be 0. i.e.,. A-1 exists when det A ≠ 0 (i.e., when A is nonsingular); A-1 does not exist when det A = 0 (i.e., when A is singular) WebFeb 6, 2024 · To multiply matrix A by matrix B, we use the following formula: A x B =.
