If Ais Hermi-tian, that is, if A∗ = A, where the asterisk denotes conjugate transpose, then the eigenvalues of the matrix are real and hence α∗ = α, where the asterisk denotes the conjugate in the case of a complex scalar.

WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A). WebThis is a 3 by 3 matrix. And now let's evaluate its determinant. So what we have to remember is a checkerboard pattern when we think of 3 by 3 matrices: positive, negative, positive. So first we're going to take positive 1 times 4. So we could just write plus 4 times 4, the determinant of 4 submatrix.
