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