The inverse of a 2 × 2 matrix is given by swapping the diagonal entries, negating the off-diagonal entries, and dividing by the determinant: (a c b d)−1 = 1 ad − bc( d −c −b a)Don't invert the matrix. Almost always, the thing you're using the inverse to accomplish can be done faster and more accurately without inverting the matrix. Matrix inversion is inherently unstable, and mixing that with floating point numbers is asking for trouble. Saying C = B . inv(A) is the same as saying you want to solve AC = B for C.where I is the 2× 2 identity matrix 1 0 0 1!. That is, multiplying a matrix by its inverse produces an identity matrix. Note that in this context A−1 does not mean 1 A. Not all 2× 2 matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular.
