Determinant of matrix in index notation

WebThe determinant of a 2x2 matrix. is Notice the difference in notation between the matrix and its determinant: matrices are typically enclosed with square brackets whereas determinants of matrices are enclosed by straight lines. The determinant is a scalar quantity. It contains much information about the matrix it came from and is quite useful ... The determinant is closely related to two other central concepts in linear algebra, the eigenvalues and the characteristic polynomial of a matrix. Let be an -matrix with complex entries with eigenvalues . (Here it is understood that an eigenvalue with algebraic multiplicity μ occurs μ times in this list.) Then the determinant of A is the product of all eigenvalues, The product of all non-zero eigenvalues is referred to as pseudo-determinant.
