Calculator below computes inverse matrices via adjugate matrix. Some basic theory is placed under the calculator

The inverse of a square matrix A, sometimes called a reciprocal matrix, is a matrix such that

This calculator uses adjugate matrix to compute matrix inverse like

**Adjugate matrix** is the transpose of the cofactor matrix of A.

Cofactor of of A is defined as

where is a minor of .
