In linear algebra, a minor of a matrix A is the determinant of some smaller square matrix generated from A by removing one or more of its rows and columns. Minors obtained by removing just one row and one column from square matrices (first minors) are required for calculating matrix cofactors, which are useful for computing both the determinant and inverse of square matrices.
The entries form the main diagonal of a square matrix. For instance, the main diagonal of the 4×4 matrix above contains the elements a 11 = 9, a 22 = 11, a 33 = 4, a 44 = 10. In mathematics, a square matrix is a matrix with the same number of rows and columns. An n-by-n matrix is known as a square matrix of order .
The antidiagonal (sometimes counter diagonal, secondary diagonal (*), trailing diagonal, minor diagonal, off diagonal, or bad diagonal) of an order square matrix is the collection of entries , such that + = + for all ,. That is, it runs from the top right corner to the bottom left corner.
The Universal Basketball Association (UBA) is a semi-professional men's basketball minor league in the United States that began play in 2009. The league typically play a Spring season schedule. Teams are split into geographical divisions, from Georgia, Indiana, Kentucky, North Carolina, Ohio and Texas.
Fifth Third Field is a Minor League Baseball stadium in Toledo, Ohio, United States. The facility is home to the Toledo Mud Hens, an International League team and the Triple-A affiliate of the Detroit Tigers. The stadium seats 10,300 and opened in 2002. It hosted the 2006 Triple-A All-Star Game and home run derby. [6]
A square matrix derived by applying an elementary row operation to the identity matrix. Equivalent matrix: A matrix that can be derived from another matrix through a sequence of elementary row or column operations. Frobenius matrix: A square matrix in the form of an identity matrix but with arbitrary entries in one column below the main diagonal.

In mathematics, an anti-diagonal matrix is a square matrix where all the entries are zero except those on the diagonal going from the lower left corner to the upper right corner (↗), known as the anti-diagonal (sometimes Harrison diagonal, secondary diagonal, trailing diagonal, minor diagonal, off diagonal or bad diagonal).
