WebInverse of Matrix. Inverse of Matrix for a matrix A is denoted by A-1.The inverse of a 2 × 2 matrix can be calculated using a simple formula. Further, to find the inverse of a matrix of order 3 or higher, we need to know about the determinant and adjoint of the matrix. WebFor example, the determinant of [1 0] = 1, the determinant of [2 0] = 2, and the determinant of [2 0] = 4. [0 1] [0 1] [0 2] Notice with each step, I multiplied a single row by 2, and the determinant increased by a factor of that scalar 2.
