WebFirst, you can refer to rows or columns of a matrix being "linearly independent" but not really the matrix itself. Now if the rows and columns are linearly independent, then your matrix is non-singular (i.e. invertible). Conversely, if your matrix is non-singular, it's rows (and columns) are linearly independent. WebConclusion. The inverse of A is A-1 only when AA-1 = A-1A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all.
