WebThe MINVERSE function returns the inverse matrix for a matrix stored in an array. Note: If you have a current version of Microsoft 365, then you can simply enter the formula in the top-left-cell of the output range, then press ENTER to confirm the formula as a dynamic array formula. Otherwise, the formula must be entered as a legacy array ... WebNow the determinant of this matrix is $1$. And if you rotate the frame {2} back to {1} you see that the matrix obtained is nothing but the transpose of the matrix. But wait isn't the transformation from {1} to {2] and the transformation from {2} to {1} inverse operations?
