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...
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 ...

We can only compute determinants of square matrices of the form NxN - this means, matrices 2x2, 3x3, 4x4, etc. For a general 3 by 3 matrix of the form: $$M = \begin{pmatrix} a_{1} & a_{2} & a_{3} \\ b_{1} & b_{2} & b_{3} \\ c_{1} & c_{2} & c_{3...

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.
