# Calculator to compute the adjugate matrix NxN

The calculator computes the adjugate matrix of a given NxN matrix and uses the result to compute also the inverse matrix. The calculator shows the calculation of every element of the adjugate matrix. The input field N defines the number of rows and columns. The input field digits is for setting the number of displayed digits. With setting of N the related matrix field will be displayed for input of the matrix elements. With 'Start calc' the computation of the adjugate and inverse matrix starts.

### Computation of the adjugate matrix

$A=\left(\begin{array}{cccc}{a}_{11}& {a}_{12}& \dots & {a}_{1N}\\ {a}_{21}& {a}_{22}& \dots & {a}_{2N}\\ & ⋮\\ {a}_{N1}& {a}_{N2}& \dots & {a}_{NN}\end{array}\right)$

Matrix dimension N =

Number of digits =

Enter the matrix elements: a11, a12, ...

The given matrix is:
