Definition of Matrix Inverse
easy
What is the inverse of a square matrix A?
A
A matrix A⁻¹ such that A + A⁻¹ = I, where I is the identity matrix
B
A matrix A⁻¹ such that A⁻¹ = Aᵀ, which holds for all square matrices with nonzero determinant
C
A matrix A⁻¹ such that det(A⁻¹) = det(A), preserving the determinant under inversion
D
A matrix A⁻¹ such that AA⁻¹ = A⁻¹A = I, where I is the identity matrix
