text: Also, there are two types of denotations in use in literature: by the minor associated to ordered sequences of indexes I and J, some authors mean the determinant of the matrix that is formed as above, by taking the elements of the original matrix from the rows whose indexes are in I and columns whose indexes are in J, whereas some other authors mean by a minor associated to I and J the determinant of the matrix formed from the original matrix by deleting the rows in I and columns in J. Which notation is used should always be checked from the source in question.
