Hey there,
I am trying to calculate C, as A=[1 2 3]; B=[1 2 3;4 5 6;7 8 9]; n=3
C=Sigma(i=1 to 3)Sigma(j=1 to3 )A(i)B (i,j)A(j)
Tell me Matlab code to calculate C. Thanks in advance

A=[1 2 3];
B=[1 2 3;4 5 6;7 8 9];
s=bsxfun(@times,bsxfun(@times, B,A),A');
s=sum(s(:))

clc
clear
A=[1 2 3];
B=[1 2 3;4 5 6;7 8 9];
for j=1:3
for i=1:3
c(i,j)=A(i)*B(i,j)*A(j);
end
end
c=sum(sum(c))
