Hi sayfee,

here is your code. I tested it for all possible values and it is working fine.

***************************************************************************
clear all;
f=[1 2 3 4];
c=[1 2 3 4 ; 5 6 7 8; 9 10 11 12; 13 14 15 16];
n = [0 1 2 3];
bb = zeros(4,4);
for k = 1 : 4
%k = 1; % just for test
%m = 2; % just for test
for m = 1 : 4
bb(k,m) = sum(f(m).*c(k,:).*n);
end % m
end % k
bb

Don't forget to press help me,

Cheers,
MAK
