Check the following piece of code.
r = magic(5);
w = bartlett(5);
for j=1:10
b1(j)=sum(r(1,:).*w'*j);
b2(j)=sum(r(2,:).*w'*j);
b3(j)=sum(r(3,:).*w'*j);
b4(j)=sum(r(4,:).*w'*j);
b5(j)=sum(r(5,:).*w'*j);
end
b = [b1;b2;b3;b4;b5];
each b1,b2,b3,b4,b5 is a vector of size 1x10 and the final result I am looking for is a vector b of size 5x10 .
I was wondering if there is a more robust way to create b rather than the paradigm above.

d=sum(bsxfun(@times,repmat(bsxfun(@times,r',w)',1,1,10),reshape(1:10,1,1,[])),2)
b=d(:,:);

This is really strange but I keep on getting the same error,
Error using ==> repmat
Too many input arguments.

By splitting each function in different parts and then combining them the final result is the one I am looking for! I still dont get why my MATLAB version dont want to compile the whole thing but its ok! Anyway thanks a lot for you time and effort !
