Anyone able to help me verify?

Consider a sequence of real-number r1, r2, ....,rN

Using this we create an (N * N) square matrix R such that the (i, j)th element of R is given by rK , where k = min(i,j), i = 1, 2, ...., N ; j = 1, 2, .....,N

A. Write the matrix R in terms of its elements. Clearly, show at least the top 3 × 3 part

and all the elements on the four corners.

r11 r1 2 r13 ------ r1N * x1 = b1

r21 r22 r23----- -r2N * x2 = b2

r31 r32 r33--------r3N * x3 = b3

ri1 ri2 ri3-------riN * xj = bj

rm1 rm2 rm3------ rmn * xN = bN

B. Is this a symmetric matrix?

yes?

A = A^T
