Indeed, we will exploit the Wigner-Eckart theorem over and over again. The determinant of a square matrix is a number associated with the matrix, which is fundamental for the study of a square matrix; for example, a square matrix is invertible if and only if it has a nonzero determinant and the eigenvalues of a square matrix are the roots of its characteristic polynomial, . (1) This document contains a collection of problems in introductory and advanced matrix calculus. The order (or size, or dimension) of a matrix is written as “m × n” where m = the number of rows, and n = the number of columns. Proof. Davis California, 2013.
