Inverse NxN Matrix Calculator

Online Calculator Inverse Matrix

The calculator computes step-by-step the inverse matrix of a NxN matrix with the Gauss-Jordan method and via the adjugate matrix.

A= ( a11a12a1N a21a22a2N aN1aN2aNN )

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.
