Best answer 1 votes 1 votes In linear algebra, a minor of a matrix A is the determinant of some smaller square matrix, cut down from A by removing one or more of its rows or columns. Minors obtained by removing just one row and one column from square matrices (first minors) are required for calculating matrix cofactors akash.dinkar12 answered Mar 30, 2017 • selected Mar 30, 2017 by srestha akash.dinkar12 comment Share Follow See all 2 Comments See all 2 2 Comments reply shraddha priya commented Apr 7, 2017 reply Follow Share @akash.dinkar12 @srestha Could you show with an example how to find minor of a rectangular matrix by removing one or more of its rows or columns?
