Invm Function

Description

The Function \(Invm\) inverts a quadratic, not singular matrix.

You can only find an inverse if it is a quadratic and not a singular matrix. Whether it is a non-singular matrix, you can check by calculating the determinant. To do this, use the function \(Det () \).

If \(Det () \) returns zero as a result, the matrix is singular and can not be inverted.

The value of the determinant is 0 if one of the following statements is true

All elements of a row or column are null

Two rows or columns are identical

Two rows or columns are proportional
