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
Regards & a million thanks

Hello,
"matrix R such that the (i, j)th element of R is given by , where , i = 1, 2, ...., N ; j = 1, 2, .....,N" simply means that "the (i, j)th element of R is (i=1,...,N;j=1,...,N)."
For example, the (2, 3)th element of R(usually denoted ) is . Since 2 is less than 3, . Thus, the (2, 3)th element of R is .
