The calculator computes step-by-step the inverse matrix of a NxN matrix with the Gauss-Jordan method and via the adjugate matrix.
Note:
The computer does not verify the invertibility or the conditioning of the matrix. A valid result is when the last computation step has the identity matrix on the left. Otherwise, can possibly a valid result produced by interchanging rows or columns.
Enter the matrix elements for matrix A: a1,1, a1,2, ...
The entered matrix is:
