This matrix has an equal number of rows and columns. Example: square matrix of the order 2. 4 3 5 8 Square matrix of the order 3. 6 2 4 3 8 7 2 4 6 Identity matrix It is a square matrix that has the principal diagonal elements as 1 and others as 0. Example: Identity matrix...
is a 2 × 3 matrix. A matrix withnrows andncolumns is called asquare matrix of ordern. An ordinary number can be regarded as a 1 × 1matrix; thus, 3 can be thought of as the matrix [3]. A matrix with only one row andncolumns is called a rowvector, and a matrix with only ...

Thedeterminantof a matrix is simply a useful tool. Like its name suggests, it 'determines' things. When doing matrix algebra, orlinear algebra, the determinant allows you to determine whether asystem of equationshas a unique solution.
Perturbation of identityRecently Brent et al. presented new estimates for the determinant of a real perturbation I + E of the identity matrix. They give a lower and an upper bound depending on the maximum absolute value of the diagonal and the off-diagonal elements of E, and show that ...
