The inverse of a square matrix A is the matrix A-1 such that
A A-1 = I
For example, if
| A = |
| , then A-1 = |
|
| because A A-1 = |
|
| = |
|
To get the inverse of a square matrix A, use the following formula
| A-1 = | 1 | adj(A) |
| det(A) |
If the determinant of the matrix is 0, the matrix doesn't have an inverse and it's called a singular matrix.
You can try to find out the inverse of a matrix (if any) by using the online calculator above.
