9. Prove that, if there exist an Hadamard matrix of order n., then there exist an Hadamard matrix of order 2n 9. Prove that, if there exist an Hadamard matrix of order n., then there exist an Hadamard matrix of order 2n
Compute the determinant of the Hadamard matrix (which is also the volume of a hypercube in R4):
Let U and V be nxn orthogonal matrices. Explain why UV is an orthogonal matrix. [That is, explain why UV is invertible and its inverse is (UV)'.] Why is UV invertible? O A. Since U and V are nxn matrices, each is invertible by the definition of invertible matrices. The product of two invertible matrices is also invertible. OB. UV is invertible because it is an orthogonal matrix, and all orthogonal matrices are invertible. O c. Since U and V...
