# coffg

Co-factors of a matrix of polynomials or rationals

### Syntax

[tC, d] = coffg(M)

### Arguments

- M
square matrix of numbers or polynomials or rationals, with real or complex coefficients.

- tC
square matrix of the type of

`M`

: Transposed co-matrix of`M`

, such that`tC/d`

is equal to`inv(M)`

.- d
scalar: determinant

`det(M)`

, with the`M`

's data type and encoding.

### Description

`coffg(M)`

computes co-factors of `M`

, and returns
the transposed co-matrix `tC`

.

When `M`

has a single component, `tC`

is
`1`

and `d==M`

For large matrices, calculations may be slow. |
