Using MS Excel in Finding the Inverse Matrix
Find the inverse or A-1 a) Enter the matrices A into the Excel sheet as: Notice that Matrix A is in cells B2:D4 b) We find the inverse of matrix A by
2.5 Inverse Matrices
Not all matrices have inverses. This is the first question we ask about a square matrix: Is A invertible? We don't mean that we immediately calculate A.
