: Prove that the sum of the three variables of the sum exponent f(x) = Σe is strictly convex. For this
i=1
purpose, compute the Hessian matrix of the function f(x).
Determined the eigenvalues of the matrix (A) given below? A=[1 0 4; 0 4 0; 3 5 -3]
(Cayley-IHamilton Theorem) The Cayley-Ilamilton theorem is a powerful theorem in
Linear algebra that states: every square matrix of real numbers satisfies its own char-
acteristic equation. For 2 x 2 matrices this can be seen in the following way. First, we
introduce the trace of the matrix
tr A
41,1 +22
and the determinant
det A = a11a22 - 41,22,1-
Then, the chacteristic polynomial is the quadratic given by
p(A) = x – (tr A)A + (det. A).
Then, for any 2 x 2 matrix, if you plug it into this polynomial, you should always get
a zero matrix.
c_h_test Function:
Input parameters:
• a single 2 x2 matrix for which you would like to test the Cayley Ilamilton
Theorem
Local Variables:
• two scalars to represent the trace and determinant
Output parameters:
a single 2 x2 which is the result of evaluating the charcteristic polynomial
at A (note: think carefully about the constant term)
A possible sample case is:
> mat_B = c_h_test([3, 2 ; 2, 0])
mat B =
0 0

Verify that a matrix multiplied by a column vector is simply a linear combination of the columns of the matrix. Namely, if the columns of the matrix A are a_1, a_2, .. a_n and the vector x is (x_1,... x_n), then Ax = x_1 a_1 + ... + x_n a_n. Explain why this is simply the outer product way of multiplying A and x.arrow_forward. The determinant of an n X n matrix can be used in solving systems of linear equations, as well as for other purposes. The determinant of A can be defined in terms of minors and cofactors. The minor of element aj is the determinant of the (n – 1) X (n – 1) matrix obtained from A by crossing out the elements in row i and column j; denote this minor by Mj. The cofactor of element aj, denoted by Cj. is defined by Cy = (-1y**Mg The determinant of A is computed by multiplying all the elements in some fixed row of A by their respective cofactors and summing the results. For example, if the first row is used, then the determi- nant of A is given by Σ (α(CI) k=1 Write a program that, when given n and the entries in an n Xn array A as input, computes the deter- minant of A.
