Definition

Minor

A minor of an element of a matrix is defined as the determinant of the submatrix that results from the -th row and -th column from .

Example

Consider a matrix :

To calculate the minor (i.e., the minor of the element in the first row and the second column):

Remove the first row and the second column:

The submatrix is:

Compute the determinant of the submatrix:
