Inverse

Usage

• Inverse[m] gives the inverse of a square matrix m.

Notes

• Inverse works on both symbolic and numerical matrices.

• For matrices with approximate real or complex numbers, the inverse is generated to the maximum possible precision given the input. A warning is given for ill-conditioned matrices.

• Inverse[m, Modulus->n] evaluates the inverse modulo n.

• Inverse[m, ZeroTest -> test] evaluates test[ m[[i, j]] ] to determine whether matrix elements are zero. The default setting is ZeroTest -> (#

0 &).

• A Method option can also be given. Possible settings are as for LinearSolve.

• See Section 1.8.3 and Section 3.7.6.

• Implementation notes: see Section A.9.4 and Section A.9.4.
