Kll7-4 matrix is forming. How can I create the other matrix?

Answer 1

[Andrei Bobrov]

m = [1.2000    2.4000    1.3000
    2.3000    1.5000    1.0000];
r = [0.2000    0.4000    0.3000];

K = permute(m,[2,3,1]).*permute(m,[3,2,1]).*...
                    (hankel([0,r(1:2)],[r(2:3),0]).*~eye(3)+eye(3)); % MATLAB >= R2016b

for MATLAB < R2016b

rr = triu(ones(3),1);
rr(rr > 0) = r;
mm = bsxfun(@times,permute(m,[2,3,1]),permute(m,[3,2,1]));
K = bsxfun(@times,mm,rr + rr.' + eye(3));

How to write in i and j format?

[Muhendisleksi]

What does [2,3,1] and [3,2,1] mean?

[Andrei Bobrov]

Please read about function permute from MATLAB

Answer 2

[Santhana Raj]

Try making

BNdog=[4 7];

instead of [4 4]
